Superior electrical performance:
Using the original raw material formula, the unique chemical co-precipitation process, the unique sintering, double-face vertical grinding pads and fully automatic patented aluminum spraying technology, the produced resistor chip guarantees its high current tolerance and also takes into account its aging characteristics. It can be installed in various insulation media, and the resistors are common to both AC and DC. The company has successfully developed a high-gradient resistor with a potential gradient of 350V / mm, which reduces the insulation level and meets customers' design requirements for miniaturization of GIS surge arresters.
