Insulation protection
Provide an insulating enclosure for high - voltage electrical equipment such as 15kV live bushings. It can prevent personnel from accidentally touching the live parts, avoiding electric shock accidents and ensuring the safety of operators. At the same time, it can prevent external conductive substances from bridging on the live body, thus avoiding short - circuit faults.
Dust and moisture prevention
Protect the non - live joints, preventing the intrusion of dust, water vapor, etc. It avoids the reduction of electrical performance and the occurrence of faults due to dust accumulation or moisture ingress, and prolongs the service life of the equipment.
Sealing protection
When the busbars and cable joints have reserved spare outlets, use insulating end caps to seal them, maintaining the stability of the internal environment of the equipment and preventing foreign objects from entering and affecting the normal operation.
