1KV thermal shrinkable busbar protective bushing 35
Inquire NowDescription
The 1KV thermal shrinkable busbar protective bushing 35 is a high-performance insulation solution designed for electrical bus bars operating at voltages up to 1KV and beyond. Made from radiation cross-linked polyolefin, this protective bushing exhibits exceptional insulating properties while being flexible and flame retardant. It is ideally suited for various applications such as rectangular, square, and round bus bars, inline bolted connections, and metal-clad switchgear, ensuring reliable insulation and protection in electrical systems. The innovative thermal shrinkage principle enhances its mechanical strength and resistance to chemical solutions and aging, making it a durable choice for demanding environments.
