Composite crossarm insulator also called polymer cross arm insulator and normally used for urban power networks, can reduce the insulator materials and financial.

Composite crossarm insulator is one main of medium voltage and high voltage insulator, normally used for 10kv to 110kv power lines, usually used on distribution lines.

Composite crossarm insulator or cross-arm composite insulator used for the urban net rebuild can effectively solve the shortage of corridor in urban power lines, reduce the pole height and economy lots of financial and material resources.

Composite crossarm insulator can installed poles with cross arm insulator pins and nuts, can be divided into outdoor insulator and indoor insulator.
