Model and product representation of 35kV and below power cables:

1. Use the capital of the first letter of Chinese pinyin to indicate the insulation type, conductor material, inner sheath material and structural characteristics. If Z represents paper (Zhi)

； L stands for aluminum (LV); Q stands for lead (Qian); F stands for phase separation (Fen); Zr stands for flame retardant (zuran); NH stands for refractory (Naihuo)

2. The composition of the outer sheath is represented by two digits. No number means no armor layer and no outer coating. The first digit indicates armor, and the second digit indicates armor

The number represents the outer cover, for example, the outer cover of thick steel wire armored fiber is represented as 41.

3. The cable models are arranged according to the cable structure, and the general sequence is: insulating materials; Conductor material; Inner sheath; Outer sheath.

4. Cable products are indicated by model, rated voltage and specification. The method is to add a number indicating the rated voltage, number of cores and nominal cross-sectional area after the model

Arabic numerals. For example, vv42-10 3 × 50 refers to copper core, PVC insulation, thick steel wire armor, PVC sheath, rated voltage 10kV

3-core power cable with nominal cross-sectional area of 50mm2.

Code and meaning of each part of power cable model

1. Insulation type: V stands for polyvinyl chloride; X stands for rubber; Y stands for polyethylene; YJ stands for cross-linked polyethylene; Z stands for paper.

2. Conductor material: l stands for aluminum; T (omitted) stands for copper.

3. Inner sheath: V represents PVC sheath; Y polyethylene sheath; L aluminum sheath; Q lead sheath; H rubber sheath; F neoprene sheath.

4. Features: d no trickle; F phase separation; CY oil filling; P lean oil dry insulation; P shielding; Z DC.

5. Control layer: 0 none; 2 double steel strip; 3 fine steel wire; 4 thick steel wire.

6. Outer cover: 0 none; 1. Fiber coating; 2. PVC sheath; 3 polyethylene sheath.

7. Add Zr before the code of flame retardant cable; NH is added before the code of fire-resistant cable.

Model and product representation of oil filled cable

The model of oil filled cable consists of product series code and code of each part of cable structure. Self contained oil filled cable product series code cy. Outer sheath structure

From the inside to the outside, it is represented by the code combination of reinforcement layer, armor layer and outer coating layer. Insulation type, conductor material, code of inner sheath and arrangement of each code

The sequence and product representation method are the same as that of 35kV and below power cables. Such as cyzq102 220 / 1 × 4 indicates copper core, paper insulation, lead sheath

Self contained oil filled cable with radial reinforcement of copper strip, no armor, PVC sheath, rated voltage of 220kV, single core and nominal cross-sectional area of 400mm2.

The code meaning of outer sheath of oil filled cable is

1. Reinforcing layer: 1 represents radial reinforcement of copper strip; 2 represents stainless steel with radial reinforcement; 3. Radial reinforcement of steel strip; 4. Radial and narrow stainless steel strip

Vertical reinforcement.

2. Armor layer: 0 no armor; 2. Steel tape armor; 4 thick steel wire armor.

3. Outer coating: 1 fiber layer; 2. PVC sheath; 3 polyethylene sheath.
