10KV-100KV Composite Cross- Arm Used Insulators
Specifications
10KV-100KV Composite cross- arm used insulators are applicable to urban power network reconstruction where streets are narrow.
Composite cross- arm used insulators are applicable to urban power network reconstruction where streets are narrow. It can take advantage of urban narrow power distribution corridor, lower the necessary height of the pole or tower. With high bending strength, they can avoid rupture accident taken place for porcelain insulators. moreover, they are all good pollution resistance.
