4 185 1X95 low voltage cable head practice?

4 What is the practice of 185+1x95 low-voltage cable head? The nominal diameter of 185 is not less than, usually between 54mm and 57mm.

The cross-section is 3x185mm + 1x95mm and the current carrying capacity of the cable is 343a. Driveable power = root number 3 x 380v x 343a x power factor) = 180559w.

YJV or 1 1x185 copper or aluminum core The approximate outer diameter of a single-core XLPE insulated PVC sheathed low-voltage power cable is: 23 mm;

YJV or 1 2x185 copper or aluminum core The approximate outer diameter of a single-core XLPE insulated PVC sheathed low-voltage power cable is: 36 mm.

Extended information: Paper insulated cable is a cable with impregnated cable paper as the insulating layer, which is collectively referred to as paper insulated cable. According to the situation of paper impregnation, it can be divided into: oil-impregnated paper insulated cable; dry-insulated cables; No trickle cables.

Cables made of thermoplastic extruded cross-linking with insulation, collectively known as plastic cables, are widely used. Plastic cables can be divided into three types: PVC cables, polyethylene cables and XLPE cables.

Cables with natural styrene-butadiene rubber, butyl rubber and ethylene propylene rubber as insulation are called rubber cables. The low-voltage cable with a voltage level of 1kV can use paper insulated cable and plastic cable, and more plastic cables are used; Low-voltage cables with voltage levels of kV mostly use rubber cables.

Summary. Hello dear Hello Glad to ask you about the service <>

How to deal with 3x (4 185 + 1x95) cables, ask you the answer: 1. Manual peeling method: This method mainly strips the outer skin of waste wires and cables through manpower, and only obtains the non-ferrous metal copper inside.

The labor cost of this method is relatively large, and this method is only suitable for a small amount of wire and cable treatment at present. 2. Mechanical stripping method: this method replaces manpower through wire stripping machine equipment to remove the outer skin of waste wires and cables.

It is a semi-mechanized operation, because it requires a human person to carry out the operation. Labor intensity is high. Currently, the stripper equipment is only suitable for cable wires as well as single-strand square wires.

3. Incineration method: This method is to burn the outer skin of the wire and cable, because the wire skin is combustible, the incinerated copper can be directly incinerated. However, this method has two drawbacks, one is that it will produce harmful gases, which will seriously cause air pollution; Second, incineration will lead to serious oxidation of the surface of the copper wire, reducing the rate.

Therefore, such methods are expressly prohibited. <>

3x (4 185 + 1x95) cable how to deal with, ask you the answer: 1, manual peeling method: this method is mainly through the way of manpower, the waste wire and cable skin is stripped off, only to obtain the inside of the fierce let Kai color metal copper branch call.

The labor cost of this method is relatively large, and this method is only suitable for a small amount of wire and cable treatment at present. 2.

4. Mechanical crushing method: This method is to peel the mechanical wires and cables by crushing, and then use water washing or air flow differentiation and electrostatic separation to separate the copper from Changchang. There are many types of this kind of processed wires and cables, and the output is high, and the application rate is relatively large.

5. Chemical method: It is mainly to soak the wires and cables through chemical solutions to decompose copper. However, this method has a high cost and high pollution, so it is not really applied.

6. Freezing method: This method uses refrigerant liquid nitrogen to freeze the wires and cables, and then the brittle wires and cables are broken and vibrated to separate the copper and the outer skin. This method is more costly.

How to explain 3x (4 185 + 1x95) cables.

4 185 + 1 95) is the specification of the cable, which means that there are 5 cores per mu of the cable, of which 4 cores are 185 square millimeters and 95 square millimeters. Generally, 185 wire is the main line core connected to the three-phase power supply, and 95 is used for the grounding of the ground core. The cable is supplied with TN-S power supply system, that is, a three-phase five-wire power supply system.

The product standard for low-voltage power cables is "GB GB T rated voltage 1kV (UM=to 35kV(UM=extruded insulated power cables and accessories) Part 1: Rated voltage 1kV (UM=and 3kV (um=cables).
