Cross arm
- Category： Power fitting
Welcome to OEM and Let us know if you need further details or assistance!
Application:Electrical cross arm is also named power pole cross arms, utility pole cross arms, telephone pole cross arms, iaht pole cross arms orcrossarms for short. in diferent application setups, there are diferent configuraions for the electrical cross arm. For instance, power polecross arms are connected with the pin insulator by insulator pin, and the insulator connects with the wire to realize the power delivery.
