ceramic insulator

Ceramic insulator provides stronger resistance against thermal shock, greater mechanic and electric strength and reliable insulation.

The cube BN grinding wheel was adopted to grind electric ceramic insulator, and the residual stress of insulators was analysed by the X-ray diffraction (XRD) technique.

Ceramic insulator is widely used in alternating and direct current transmission system. But there exist some problems when using ceramic insulator in direct current transmission system.
