The braided flat copper wire of wind power project is also called equipotential bonding wire, which mainly plays the role of grounding. The model and specification are determined according to the actual situation of the project. For example, 50 mm2, 70 mm2 and 125 mm2 of tinned copper braid are common specifications.
The braided flat copper wire is also called copper conductive strap. Generally, the braided flat copper strap used for grounding will be covered with a layer of yellow-green heat-shrinkable tube on the surface for three reasons:
1. The outer layer of the copper conductive strap can be insulated and protected against electric shock after being sleeved with a heat-shrinkable tube, and prevent the copper conductive strap from being overlapped with other connecting wires to cause short circuit, making the equipment safer to use.
2. Protect the copper conductive strap itself from the pollution of the surrounding environment. Because the copper conductive strap is exposed to the air, adding an insulating layer can effectively prevent dust and other pollution.
3. Dust pollution will slowly defecate the surface of the copper conductive strap and have a corrosive effect on the copper wire. This can be effectively avoided and its service life can be extended by adding an insulating layer.
