90d wire and cable

D stands for diameter, D9O is the specification comparison table of bending radius of pipe and cable with diameter of 9o: the bending radius of cable can be explained from two aspects, one is the bending radius of the cable itself, and the second is the bending radius of the cable during construction and laying. The cable is integrated according to its section, and the unit is square millimeter. For example, 90 cables have a cross section of 90 mm2.

Wire and cable community

There are marks on the cable sheath. For example, a 50mm2 4-core cable is marked as 3 * 50, 1 * 25. 3 * 50 indicates that three live wires are 50mm2, one zero wire is 25mm2, and there are also five-core cables. Add a live wire. If the mark is not clear, you have to peel off the sheath and measure the outer diameter with a vernier caliper (the thicker one is the live wire). The diameter of the cable is as large as it is

Specification and model of cable and wire

The cable specification and model are written on the insulating skin of each cable. The cable specification and model actually represent the number of cores and cross-sectional area of the cable, and are also a reference data for cable selection. The number of each cable letter has a special meaning. So when we look at the cable specification, we must clearly see the number of cable specification and model. The cable specification and model so far have Bx copper core rubber insulated wire. Bsf copper-aluminum core neoprene insulated wire, bx2 copper-core rubber insulated flexible wire, bv copper-aluminum core PVC wire, in addition, bv, VB, and LVV belong to copper-aluminum core PVC insulated, polyethylene sheathed round wire, bv2 copper-aluminum zinc PVC insulated flexible wire, bv105 copper-core heat-resistant 150 degree PVC insulated flexible wire, v copper-core PVC insulated flexible wire, rvb copper-core PVC insulated flexible wire, rvs copper-core PVC insulated flexible wire, Tx copper core rubber insulated braided round flexible wire, bbx copper core rubber bonded glass braided wire, bbla rubber insulated glass bonded braided wire.
