Conductive cross arm (copper-steel composite plate conductive cross arm)

Stainless steel pull ring

Conductive cross arm

The composition of the conductive cross arm: the conductive cross arm is made of electrode spray ring, electrode pull ring, electrode chuck, electrode blowing device, electrode clamping device, cross arm body, water inlet pipe, water return pipe, into the oil pipe, metal hose, water-cooled cable connection plate.
Conductive arm material using copper-steel composite plate is the outer layer of copper plate inner layer with steel plate by explosion welding together.
Conductive arm is usually made into a rectangular shape, the outer copper plate is used to conduct electricity, the inner steel plate is used as a support arm. Cooling methods are hollow sandwich water-cooled and whole water-cooled two, the internal are filled with cooling water, in order to make the cooling effect a little better will be made into the upper and lower cross arm compartment, cooling water from the lower layer into, from the upper layer out. Use copper plate instead of conductive copper tube. Can greatly increase the conductive area, but also greatly reduce the reactance, resistance value, so that the active power to improve.
