Cables are used to transmit electrical (magnetic) energy, information and electromagnetic can be transformed. The broad wire and cables are also referred to as cables. The narrow cable refers to the insulating cable. It can be defined as a collection of the following parts;One or multi -root insulation wires, as well as the coverage layer that they may have, the total protective layer and the outer care layer, and the cable can also have an additional insulation conductor.

The national standard algorithm should be such 120 × 0.0089 × 1, which is the area × density × length = weight 1. Therefore, it can be concluded: 1.068 kg of copper.The price of copper wire today is 59.6 kilograms.The copper price is: 63.6 yuan.2. The weight of the 120 -square -meter wire of 100 meters is about 120kg, so 1 meter is about 1.2kg. Therefore, the PVC of 1.5 Gong two should be used for 8 yuan/kg, so it is about 1.2 yuan.A total of about 64.8 yuan.About 65 yuan.
