Product Description
The resistor is suitable for circuits with AC voltage of 50HZ to 1140V and DC voltage of 1000V, mainly as high-power and high-current motor driving, braking and variable frequency braking resistors, and central neutral point grounding resistors of high-voltage transformers. The resistor element is processed into a strip element from raw materials, with holes at both ends for assembly. Insulating porcelain pieces are added between each piece, and two insulating sleeves are added to the porcelain piece to achieve good insulation and no short circuit to the ground. The resistor element is connected by argon arc welding. The electrical contact is reliable and good. The product appearance structure is divided into three types: open type, indoor protection and outdoor protection. It is suitable for high-voltage central grounding resistors in power systems and brake resistors in variable frequency speed regulation in lifting equipment. The stator voltage regulation speed regulation motor rotor external resistor is suitable for high-power, high-current motors or brake resistors.

Type
Mesh stainless steel ZX26 series
ZX26 series stainless steel resistors are suitable for electrical appliances with AC 50Hz, voltage up to 1140V and DC 1000V. They are mainly used as motor starting, braking and speed regulation and inverter braking resistors. They are safe and reliable, large capacity, corrosion-resistant, long life, and maintenance-free. They are particularly superior in matching resistors for high-power motors. The power of a single unit can reach 6KW, and it is composed of up to 22 resistor sheets.
Stainless steel strip ZX36S series
Stainless steel strip resistors are suitable for AC 50HZ voltage 1140V and DC 1000V circuits, high-voltage neutral point grounding resistors in power systems, variable frequency speed regulation brake resistors in lifting equipment, and external resistors for stator voltage and speed regulation motor rotors.
Stainless steel sheet ZX36HL series
Stainless steel sheet series resistors are suitable for AC 50HZ voltage 1140V DC 1000V circuits, mainly used as high-power and high-current inverter brake resistors, with the characteristics of safety, reliability, large capacity, and corrosion resistance. This series is built-in type and needs to be equipped with a resistor box or resistor cabinet. The built-in resistor can be assembled at will, and the box (cabinet) size can be customized as required.
