product usage:
the unt-dz low-voltage grounding resistor is mainly used for the 0.4kv low-voltage power system of a thermal power plant or the 0.66kv low-voltage power plant of a coal mine. it is a neutral point grounding resistor for low-voltage transformers.
features:
the resistor cabinet is made of cold-rolled steel or stainless steel.
the material of the resistor is made of cr20ni80 nickel-chromium alloy, so the conductivity is high, the temperature is good, the maximum use temperature can reach 1200 °c and the temperature coefficient is small, the resistance value is stable, fireproof and explosion-proof, and the reliability is high.
