Chapter 1. General Introduction The eye mold used for extrusion is an important link in the final finalization of wires and cables. The quality of wire and cable products - shape, appearance, etc. - will be directly affected by the design of the mold. The classification of extrusion molds can be directly divided into three types: extrusion, half pipe, and extrusion. The specific form of the die is as follows: 1. Extrusion die: extrusion

Today, we will briefly introduce the classification of fireproof cables. The classification is mainly based on different structures. So let's first understand the two major structural components of cables: conductors and insulators. 1. Cables mainly have copper conductors: conductors can be divided into bare copper, copper plated, copper clad steel, copper alloy, copper foil wire, etc. Bare copper --- conductor

The armouring layer of cables for electrical equipment, that is, control cables, is not only steel tape. Generally, there are the following types: copper wire braided shielding, copper tape shielding, steel tape armouring, aluminum tape armouring, and several kinds of combined composite armouring. There are many kinds of cables with complicated names. The rated voltage is low. The service voltage of these wires and cables is 450/750

On February 23, 2019, the computer cable is suitable for indoor, cable trench, pipeline and other occasions requiring non electrostatic shielding. High pressure polyethylene with small dielectric constant is used as insulation for computer shielded cable. The structure of twisted pair, screen pair, collective screen (or three wire combination, collective screen, collective screen) is adopted, which has the characteristics of low dielectric loss, strong signal transmission capability, good anti-interference performance, etc

Complete production process of cable (stranded wire) 1. Features of stranded wire 1. Good flexibility; It can reduce the damage caused by bending, vibration and swing, which is beneficial to installation. 2. Good reliability: the defects of the single wires constituting the twisted wire cannot be concentrated at the same place, so the single wire defects have more influence on the performance of the twisted wire than on the performance of a single conductor
