FORTUNE PACIFIC Load bank System Components
1. Resistor
Core Component of the Load – Dry Load Module
The dry load module, the core component of the load system, converts electrical energy into thermal energy to conduct continuous discharge tests on equipment such as generator sets and power supplies under test. Our company utilizes self-developed alloy resistor load modules. Given the safety-critical nature of dry loads—particularly their susceptibility to temperature variations—we implement rigorous quality control over temperature coefficients and heat dissipation performance. The resulting alloy resistors exhibit minimal temperature drift, gradual temperature rise, rapid heat dissipation, enhanced thermal resistance under full-load operation, and long-term stable performance. Below are the specific technical solutions and performance objectives:
1) Alloy Resistor Technology
4) Withstand Voltage:
Each resistor shall withstand DC 3000V or AC 1500V (50Hz) for 1 minute without breakdown. The operating voltage is set at 1/3 of the withstand voltage to ensure the resistor remains in good working condition without failure.
5) Cooling Fin Temperature:
The temperature of the cooling fins shall not exceed 300°C (with a maximum allowable value of 320°C), providing a sufficient safety margin to ensure the alloy resistor can operate continuously. The maximum rated temperature of the resistor is 1300°C.
6) Temperature Drift:
When the resistor temperature reaches 300–400°C, the temperature drift remains within ±2%, ensuring minimal resistance value variation under high-temperature conditions. This guarantees stable power loading across all temperature ranges.
7) Load Accuracy:
Load accuracy shall remain within ±3% across the entire temperature range (minimum to maximum operating temperatures).
8) Air Outlet Temperature:
The air outlet temperature shall not exceed 80°C (measured within 1 meter of the outlet).
2. High Voltage Load Insulation Process
In order to ensure the load safety under the condition of high voltage test, our company adopts a unique high voltage load insulation process.
Alloy resistance is the basic power consumption component of load, and the combination of alloy resistance in a certain way constitutes the power resistance module of load. Our company adopts a unique design method in the installation process of power resistance module, which greatly improves the load insulation strength, so as to solve the problem that the traditional medium and high voltage load insulation performance is insufficient and cannot be directly connected to the test circuit of high voltage generator set.
The high-voltage power resistance module of our company adopts high-strength insulation composite structure, fixed with special FRP profiles, and sealed around the power consumption resistance module, so as to effectively isolate the power resistance and the whole chassis, so that the whole power consumption module has the characteristics of high insulation strength, high temperature resistance, corrosion protection, moisture-proof and rain proof, and can adapt to various harsh environments It can maintain good insulation and reliability even under very humid conditions. At present, this resistance module technology has obtained the patent certificate of invention (Patent No.: ZL 201210304047.8).
The practice shows that the power consumption module with high-strength insulation composite structure has achieved better results than expected, thus realizing the safe and direct load test of high-voltage generator set, instead of relying on the high-power transformer to step down and then test the high-voltage generator set, which saves the cost of the test system, improves the accuracy and reliability of the test. The installation diagram of high-strength insulation composite structure is as follows:
3. Main Circuit
The main circuit of Fortune Pacific Load Bank directly controls the operation of the load part and adopts the contactor---fuse control protection mode. Each group of loads corresponds to a group of contactors---fuses. The system realizes the change of loading power through the on-off of contactor, and the fuse is used for circuit short-circuit protection.
The system uses high-voltage special vacuum contactor and fuse. Its insulation strength and creepage distance meet the specifications of high-voltage electrical appliances. It has strong arc extinguishing ability and can operate safely and reliably in the high-voltage test circuit.

FORTUNE PACIFIC Load bank System Components
1. Resistor
Core Component of the Load – Dry Load Module
The dry load module, the core component of the load system, converts electrical energy into thermal energy to conduct continuous discharge tests on equipment such as generator sets and power supplies under test. Our company utilizes self-developed alloy resistor load modules. Given the safety-critical nature of dry loads—particularly their susceptibility to temperature variations—we implement rigorous quality control over temperature coefficients and heat dissipation performance. The resulting alloy resistors exhibit minimal temperature drift, gradual temperature rise, rapid heat dissipation, enhanced thermal resistance under full-load operation, and long-term stable performance. Below are the specific technical solutions and performance objectives:
1) Alloy Resistor Technology
- Material: Nickel-Chromium Alloy (NiCr6023)
- Temperature Resistance: High-temperature rated, with a maximum operating temperature of 1,300°C
- Electrical Performance: Stable conductivity with ultra-low temperature drift (5×10⁻⁵/°C), representing cutting-edge technology in alloy resistor manufacturing.
- Resistor Structure:
- Case Material: Low-thermal-expansion, oxidation-resistant Stainless Steel 321 (1Cr18Ni9Ti)
- Filling Material: Export-grade electrical crystalline magnesium oxide powder (Sg-9), compliant with performance standard JBY-TE4088-199
- Magnesium oxide density: 3.0 g/cm³ ± 0.2
- Fasteners: Corrosion-resistant, high-temperature Stainless Steel 321 (1Cr18Ni9Ti)
- Quality Control: Stringent material traceability ensures highly consistent performance across mass-produced alloy resistors.
- Material: Stainless Steel 321
- Dimensions:
- Height: 7 mm ± 2 mm
- Thickness: 0.4 mm ± 0.2 mm
- Winding Spacing: ≤ 3 mm ± 0.2 mm
4) Withstand Voltage:
Each resistor shall withstand DC 3000V or AC 1500V (50Hz) for 1 minute without breakdown. The operating voltage is set at 1/3 of the withstand voltage to ensure the resistor remains in good working condition without failure.
5) Cooling Fin Temperature:
The temperature of the cooling fins shall not exceed 300°C (with a maximum allowable value of 320°C), providing a sufficient safety margin to ensure the alloy resistor can operate continuously. The maximum rated temperature of the resistor is 1300°C.
6) Temperature Drift:
When the resistor temperature reaches 300–400°C, the temperature drift remains within ±2%, ensuring minimal resistance value variation under high-temperature conditions. This guarantees stable power loading across all temperature ranges.
7) Load Accuracy:
Load accuracy shall remain within ±3% across the entire temperature range (minimum to maximum operating temperatures).
8) Air Outlet Temperature:
The air outlet temperature shall not exceed 80°C (measured within 1 meter of the outlet).
2. High Voltage Load Insulation Process
In order to ensure the load safety under the condition of high voltage test, our company adopts a unique high voltage load insulation process.
Alloy resistance is the basic power consumption component of load, and the combination of alloy resistance in a certain way constitutes the power resistance module of load. Our company adopts a unique design method in the installation process of power resistance module, which greatly improves the load insulation strength, so as to solve the problem that the traditional medium and high voltage load insulation performance is insufficient and cannot be directly connected to the test circuit of high voltage generator set.
The high-voltage power resistance module of our company adopts high-strength insulation composite structure, fixed with special FRP profiles, and sealed around the power consumption resistance module, so as to effectively isolate the power resistance and the whole chassis, so that the whole power consumption module has the characteristics of high insulation strength, high temperature resistance, corrosion protection, moisture-proof and rain proof, and can adapt to various harsh environments It can maintain good insulation and reliability even under very humid conditions. At present, this resistance module technology has obtained the patent certificate of invention (Patent No.: ZL 201210304047.8).
The practice shows that the power consumption module with high-strength insulation composite structure has achieved better results than expected, thus realizing the safe and direct load test of high-voltage generator set, instead of relying on the high-power transformer to step down and then test the high-voltage generator set, which saves the cost of the test system, improves the accuracy and reliability of the test. The installation diagram of high-strength insulation composite structure is as follows:
3. Main Circuit
The main circuit of Fortune Pacific Load Bank directly controls the operation of the load part and adopts the contactor---fuse control protection mode. Each group of loads corresponds to a group of contactors---fuses. The system realizes the change of loading power through the on-off of contactor, and the fuse is used for circuit short-circuit protection.
The system uses high-voltage special vacuum contactor and fuse. Its insulation strength and creepage distance meet the specifications of high-voltage electrical appliances. It has strong arc extinguishing ability and can operate safely and reliably in the high-voltage test circuit.
