NECR for transformer

2.Product use: This product used for the neutral point of transformer in 6-35KV system to realize grounding through resistors in the power system to avoid the damage when the earth fault current occurs.

3.The resistors can adopt stainless steel or nickel-chromium alloy, featuring high conductivity and high temperature resistance, with the maximum applicable temperature up to 1,400℃, small temperature coefficient, stable resistance value, corrosion resistance, flame-proof and explosion-proof performance and high reliability.

Our company can provide U.S.-made resistor discs depending on customers’ requirements. 4.Depending on different use conditions, the resistor cabinets can be divided into indoor and outdoor-type ones.

The in-line method can adopt up-in - down-out and down-in-down-out, etc., and the cabinet top is equipped with through-wall casing pipes when the up-in-down-out method is adopted. In addition, the cabinet is equipped with special lifting devices.

5.As a standard product, the THT-ZT-type neutral grounding resistor cabinet can run with resistors or reactance in parallel, able to satisfy the requirements of ever-increasing of power grids and ever-decreasing of grounding resistance.
