Products Description
With the increase of power grid capacity and cable feeder, the grounding capacitor current increases. In order to reduce the resonance generation and reduce the internal overvoltage, the application of neutral grounding resistors in medium voltage power grids is increasing. The newly developed zinc wire linear resistance neutral grounding resistor has the characteristics of large heat capacity, low temperature rise, stable resistance value, small size, safety and high reliability, and has good operation.

Products cooperation picture
1.A kind of zinc wire drying heat exchanger furnace steel structure system, relates to the furnace steel structure technical field, comprises a heat exchanger furnace steel structure main body and a base, the upper surface of the base is fixedly connected with the lower surface of the steel structure main body of the heat exchanger furnace kiln, the inside of the base is provided with a suction assembly, and the inside of the base is provided with a filtering mechanism. Through the use of air duct, thermal insulation sleeve board, foam plastic insulation board, foamed cement insulation board, exhaust pipe and one-way air valve, the heated hot air is introduced to the inside of the insulation sleeve through the air duct, and forms a layer of high temperature barrier with the insulation sleeve plate, the overall temperature of the insulation sleeve plate and the internal temperature difference of the steel structure of the heat exchanger furnace kiln is small, so as to avoid the large temperature difference and lead to the problem of heat dissipation block, and at the same time cooperate with the effect of foam plastic heat insulation board and foamed cement insulation board to improve the thermal insulation performance of the main body of the heat exchanger furnace steel structure.
