Let’s go to the learn about the AC cable

Date:2022-3-23 Author:xinchen1

Ac stands for alternating current, which is the Abbreviation of alternating current. The current size and direction of alternating current will change periodically. Another feature of alternating is that the average value of alternating current is zero within a cycle. And for cable, there are two different meaning.

One is a wire that carries electricity or information from one place to another, consisting of one or more insulated conductors and a protective coating. The second is a cordlike cable usually consisting of several or groups of conductors (at least two in each group) twisted together, insulated from each other and often twisted around a center, with a highly insulating covering covering the entire surface.

The cable has the characteristics of internal electrification and external insulation. The AC cables means: 1, the connecting cable inverter to boost transformer; 2, the connecting cabel of boost transformer to distribution unit. 3, the connecting cable of power distribution unit to grid or customer.

The type of AC cables

The first of AC cables is the model YJLV22 — 0.6/1, 3×70: 1kV three aluminum core 70mm ‘xLPE insulated PVC sheathed steel belt pin installed cable, for those cables with very large cross sections or copper core can not be used in amplitude crosslinking, because warm water flexibility is very strong. The second AC cables is model YJV22-8.7/10, 3×120:10kV grade cable, also called 10kV three copper core 120mm cross. At present, 10kV grade cable is most suitable for dry crosslinking production proccess, which will improve the quality stability of the product, and its price is also very reasonable. The third type of the AC cables is jKLYJ-6 /lO, 1X70:10KV aluminum core 70mm overhead insulated cable.

Some person will ask what is the meaning of VV22 named in the type of cable? Let me explain to you.

1, VV is PVC insulated PVC sheathed power cable;

2, YJV is xLPE insulated PVC sheathed power cable;

3, YJV22 is xLPE insulated PVC sheathed steel tape armored power cable. The types of electric wires and cables used for electrical equipment and power cables are mainly composed of the following seven parts: category, utility code, conductor code, insulating layer code, protective layer code, characteristic code, armored layer code, outer protective layer code.

AC cables

By the way, there is power cable which is very important.

A power cable is an electrical cable, an assembly of one or more electrical conductors, usually held together with an overall sheath. The assembly is used for transmission of electrical power. Power cables may be installed as permanent wiring within buildings, buried in the ground, run overhead, or exposed. Power cables that are bundled inside thermoplastic sheathing and that are intended to be run inside a building are known as NM-B (nonmetallic sheathed building cable).
