 Wire and cable for electrical equipmentOne of the five main types, how to understand the basics of wire and cable for this type of electrical equipment is also important to our technicians and medium and high voltage cables.

Wires and cables for electrical equipment, electrical appliances, electrical installation lines and control signals that directly transmit electrical energy from the distribution points of the power system to various types of equipment used in industry, agriculture, industry and mining. Wires and cables for electrical equipment in enterprises belong to this category. This type of product has a wide range of uses and many types, most of which must be combined with the characteristics of the equipment used and environmental conditions to determine the structure and performance of the product. Therefore, in addition to a large number of general products, there are many special and special products.

 Wire and cable for electrical equipmentProduct classification: usually divided into eight categories according to the use of the product. Each type of product contains a variety of cables, so this kind of electrical equipment wire and cable is relatively complex. It is hoped that through learning, our craftsmen will have a comprehensive understanding and support for it, and pay attention to its structural characteristics, performance indicators, environmental conditions, use requirements, etc. in the work process, formulate reasonable technical specifications, process flow, inspection and testing, and produce high-quality products to serve users. Eight categories of products are as follows:

1 Low-voltage power distribution electrical equipment with wires and cables mainly refers to fixed laying and mobile power wires and cables.

2 Signal and control cables mainly refer to electrical equipment wires and cables used to transmit signals or perform control operations, such as ordinary rubber, plastic insulated wires, rubber, plastic insulated flexible wires, shielded insulated wires, rubber sheathed flexible cables, etc. Between the control center and the system. For example, control cables composed of various insulating materials and sheaths, control cables for intrinsic safety circuits, low-smoke halogen-free electronic computer control cables, etc.

3 The connecting line of the instrument and equipment mainly refers to the internal installation line of the instrument and equipment. and external leads. Such as: nuclear power plant IE grade K3 instrument installation wiring cable, water conservancy project observation signal and power equipment cable, flame retardant instrumentation, fluorine insulation computer cable, etc.

4 Wires and cables mainly used for transportation refer to the supporting wires and cables of automobiles, locomotives, ships and airplanes.

5 geological resources exploration and development of wire and cable mainly refers to the use of coal, ore, and oil field exploration. Such as: oil platform cable, geological exploration cable, coal mine with flame retardant cable, mining wire and cable, etc.

6 DC high voltage cable

Mainly refers to the X-ray machine and electrostatic equipment. Such as: mainly refers to the high temperature, fire, nuclear power plant wire and cable. Such as nuclear power plant photographic light source cable, DC high voltage flexible cable, high voltage electric furnace cable, electron microscope high voltage cable.

7 Special wire and cable

High temperature cables, fluoroplastic or silicone rubber insulated and sheathed cables, mineral insulated cables, thermocouple cables and cables, high temperature sensor control cables, etc.

8 Heating cables mainly refer to wires and cables used for household heating, plant cultivation and pipeline insulation. For example: automatic control heating cable, mineral insulated heating cable, etc.
