The types and varieties of the power cable

2014-11-18 09:00:54 Tips:

The model of power cable and breed basically has the following several aspects: 

Up to and including 35 kv power cable types and products 

1. Capitalize the first letter of pinyin in Chinese said within the insulation class, conductor material, sheath material and structural features. Such as with Z represents paper (zhi) 

L on behalf of the aluminum (lv); Q represents the lead (qian); F on behalf of the split phase (fen); ZR on behalf of the flame retardant (zuran); NH on behalf of the refractory (naihuo 

). 

2. Use the figures show that the outer sheath, there are two Numbers. Without number represents without armoured layer, outer layer. The first digital representation armoured, second 

Numbers are outside, such as thick steel wire armoured fibers are represented as 41. 

3. The cable type according to the arrangement of cable structure generally in sequence as follows: insulation materials; Conductor materials; Within the sheath; Outer sheath. 

4. Cable products represented by type, rated voltage, and specification. The method is explained in after model coupled with rated voltage, some conclusions and nominal cross-sectional area 

Arabic numerals. Such as VV42-10 3 x 50 said copper, PVC insulated, crude steel wire armoured and PVC sheathed, 10 kv rated voltage, 

3 core, power cable of the nominal cross-sectional area was 50. 

Power cable type of each part and its meaning 

1. The insulation class: V represents PVC; X represents the rubber; Y represent polyethylene; YJ on behalf of the crosslinking polyethylene; Z on behalf of the paper. 

2. The conductor material: L on behalf of aluminum; T (omitted) on behalf of the copper. 

3. The inner sheath: V represents the PVC sheathed; Y PE sheathed; L aluminum sheath; Q lead sheath; H rubber sheath; F neoprene sheath. 

4. Characteristics: D don't drip; F split phase; CY oil filled; P boundary dry insulation; P block; Z dc. 

5. Control layer: 0; Two pairs of steel belt; 3 fine steel wire; 4 thick wire. 

6. The outer layer: 0 no; 1 fiber was outside; 2 PVC sheathed; 3 PE sheathed. 

7. The flame retardant cable in front of the code and ZR; Fire-resistance cable and NH before the code. 

Oil-filled cable types and products 

Oil-filled cable type by product line and cable structure of each part. The oil-filled cable products series code after CY. Outer sheath structure 

From the inside and external strengthening layer, armoured layer, outside layer code combination said. Within the insulation class, conductor material, the arrangement of the boot code and the code 

Order and the representation method of product and 35 kv and below power cable is the same. Such as CYZQ102 220/1 x 4 said copper core, paper insulation, lead sheath, 

Copper strip radial strengthen, no armoured and PVC sheathed, rated voltage 220 kv, single core, since the capacitance of the nominal cross-sectional area was 400 oil-filled cable. 

Oil-filled cable outer sheath code means 

1. Strengthening layer: 1 on behalf of the copper strip radial strengthen; 2 for stainless steel with radial strengthen; 3 steel strip radial strengthen; Four stainless steel belt radial, narrow stainless steel belt 

Longitudinal strengthened. 

2. Armoured layer: 0 without sheathed; 2 steel tape armoured; 4 crude steel wire armoured. 

3. The outer layer: 1 fiber layer; 2 PVC sheathed; 3 PE sheathed.
