The insulating housing of these products is made of high-quality silicone rubber which has good electrical insulation properties, hydrophobic properties and aging resistance. The external insulation meets the requirements of GB311.1“Insulation coordination of high voltage transmission and distribution equipment”. These products have merits such as operation reliability, no power-flow current, good anti-contamination ability, good anti-explosion performance, light weight, easy transportation, and simple maintenance etc. They are widely used in low voltage and middle voltage electrical systems.
