Wire and cable model introduction

Wire and Cable Model Introduction 1. The cable model consists of eight parts:

First, use code - not labeled as power cable, K as control cable, P as signal cable;

Second, the insulation code -Z oil-impregnated paper, X rubber, V PVC, YJ cross-linked polyethylene three, conductor material code - not labeled as copper, L is aluminum;

Fourth, the inner sheath code - Q lead package, L aluminum package, H rubber jacket, V PVC jacket fifth, derived code -D does not drip, P dry insulation;

Sixth, outer sheath code seven, special product code - TH humid tropical, TA dry tropical;

Eight, rated voltage - unit KV

Second, the naming of wires and cables, and the naming of wire and cable products have the following principles:

The complete naming of wires and cables is usually more complicated, so people sometimes use a simple name (usually a category name)

Replace the complete name with the model specification, such as "Low Voltage Cable" for all plastic insulated power cables of 0.6/1kV class.

The spectrum of wire and cable is relatively complete. It can be said that as long as the standard model specifications of wires and cables are written, specific products can be identified.

But what is its full name?

1. The contents included in the product name (1) product application or size class name (2) product structure material or type;

(3) Significant or additional features of the product are basically named in the above order, sometimes to emphasize important or additional features, to write features to the front or to the corresponding structure description.

2, the structure of the description of the order Product structure description from the inside to the outside principle: conductor -> insulation -> inner sheath -> outer sheath -> armored type.

3, Simplified In the case of no confusion, some structures describe writing or abbreviations. For example, aluminum conductors are not allowed in automobile lines and cords, so conductor materials are not described.

4. The composition and sequence of wire and cable are as follows:

[1: category, use] [2: conductor] [3: insulation] [4: inner sheath] [5: structural characteristics] [6: outer sheath or derived] - [7: use characteristics]

Items 1-5 and 7 are indicated by pinyin letters. Polymer materials are represented by the first letter of the English name. Each item can be 1-2 letters. The sixth item is 1-3 numbers.

The omitted principle in the model: Copper is the main conductor material used in wire and cable products, so the copper core code is written by T, except for bare wires and bare conductor products. Bare wire and bare conductor products, power cable products, and magnet wire products do not indicate major codes. Wire and cable and cable for electrical equipment and communication cables are also not specified, but subcategories or serial numbers are listed. The seventh item is a mark for various special use occasions or additional special use requirements, and is marked with pinyin letters after the "-". Sometimes, to highlight this item, write this item to the front. Such as ZR-(flame retardant), NH-(refractory),

WDZ-(low-smoke, halogen-free, corporate standard), -TH (for hot and humid areas), FY- (anti-termite, corporate standards), etc.

In the wire type: the letter B represents the wire, the letter V represents the polyvinyl chloride in the plastic, and the letter R represents the cord (the conductor is a number of filaments twisted together). There is no indication that the copper core symbol or hard line (common single-core conductor) is omitted.

R-connecting flexible cable (wire), soft structure.

V-insulated PVC.

V-PVC insulation V-PVC sheath B-flat (flat).

S-twisted type. A-tin or silver plating. F - High temperature resistant P-braided shield P2 - Copper tape shielded P22 - Steel tape armour Y - Prefabricated, generally omitted, or polyolefin sheathed FD - Product category designator, refers to branch cable. The standards of the Ministry of Construction that will be promulgated are represented by FZ, which are essentially the same as YJ—XLPE insulated V—PVC insulated or sheathed ZR—flame-retardant NH—refractory WDZ—halogen-free low-smoke flame-retardant WDN—no Halogen-low smoke refractory type BVV means PVC insulation, PVC jacket, copper core (hard) fabric wire. Often referred to as sheathed wire, single-core is round, double-core is flat. It is often used for surface mounted wires.

BVR represents PVC insulated, copper (soft) fabric wire. Often referred to as a cord. Because the wires are relatively soft, they are often used in the connection of electric power to the motor and the occasion where the wire is often moved slightly.

The meaning of the specification notation:

Specifications using the number of cores, nominal cross-section and voltage levels indicate:

1 Single-core branch cable specification notation: Number of cables in the same loop*(1*nominal section), 0.6/1kV,,I:^)X) Av'i#l

For example: 4*(1*185)+1*950.6/1kV1}1z"}3d*`!?&X'p7w

2 Multi-core stranded branch cable specification notation: number of identical loop cables * nominal cross section, 0.6/1kV,

For example: 4**185+1*950.6/1kV

3 Multi-core and sheathed branch cable specification notation: number of cable cores × nominal cross-T, such as: 4 × 25-T

Complete model specification notation : . J+～"j4{&d-~.~#i+^(u

Because the branch cable contains the trunk cable and the branch cable. And the two specifications are different, so there are two ways to represent it:

1 The main cable and the branch cable are separately represented,

Such as: trunk cable: FD-YJV-4*(1*185)+1*950.6/1kV

Branch cable: FD-YJV-4*(1*25)+1*160.6/1kV

This method is particularly concise at the time of design, and can easily show the difference in branch line specifications'B4{'X6m*u'

2 The trunk cable and the branch cable are shown together, such as: FD-YJV-4*(1*185/25)+1*95/160.6/1kV*M4z:`7k,z$~2O

This method is more intuitive, but it is limited to the case where the branch cable is of the same type, and it cannot represent different specifications of the branch line: Since the branch cable is mainly due to the low voltage distribution system of 1kV, the rated voltage of 0.6/1kV can be specified in the design callout. Omitted.

4. The distinction between wire and cable In fact, there is no strict boundary between "wire" and "cable". Usually, the product with a small number of cores, a small product diameter, and a simple structure is called electricity. A non-insulated product is called a bare wire. Others are called cables. A conductor with a larger cross-sectional area (greater than 6 mm2) is called a large wire. Small (less than or equal to 6 mm2) is called a small wire, and an insulated wire is also called a cloth wire.

Product Usage:

This product is used for AC rated voltage Uo/U450/750V and below power, home appliances and various mobile or electrical equipment and tools.

5. Rubber sheathed cable (1) General rubber sheathed flexible cable:

2, the cable long-term allowable working temperature should not exceed 65 °C;

3, W-derived cable with weather resistance and a certain degree of oil resistance, suitable for use in outdoor or contact with oil pollution occasions;

(b) Welder cable:

1, the product according to GB5023-1997 standard;
