Hollow Composite Insulator
This series of products is applicable to the circuit breaker, load switch, disconnector, earthing switch, instrument transformer, power transformer and bushings. Hollow composite insulator is shaped by whole injection of silicon rubber. After the electrical performance optimization and structural designing optimization, the product has excellent insulating performance and reliability. The maintenance is convenient and it has the advantage of explosion-proof, seismic resistance and pollution resistance. The products comply with IEC61109 standard.
Company Profile
Nanjing Rainbow Electric Co., Ltd. (NJREC) is a leading Chinese manufacturer and supplier of electrical insulators and transformer components. We undertake and offer reliable electrical insulators for transmission lines and substations. We also provide one-stop solutions for distribution & power transformers (oil-immersed & dry type), pad-mounted transformers, and wall-mounted applications.
Our main products include: Glass & Porcelain Insulators, Transformer Bushings (HV & LV), OIP/RIP/RIS Condenser Bushings, Wall Bushings, and Tap Changers.
Additionally, we also have anti-bird streamer shed and booster shed, heavy hammer series to ensure the stability and safety of the insulators in the environment. They both good in voltage sharing and arc conducting, to protect the insulators from getting burned and rusted.We focus on select excellent material and process reasonable design of composite insulator.
