Cable APvVng (A) -LS is a conductive wire with a different type of insulation. The shell of the product is made of cross-linked polyethylene. Depending on the nominal voltage level, two types of material crosslinking are distinguished: using silanes (for low voltage) and using peroxides (for high voltage).
Regardless of the type of stitching of the insulating layer, polyethylene is superior to paper in all its characteristics. For this reason, cables of the APvVng (A) -LS type are pushing out paper-insulated wires from the market.
Wire construction and features
The wire structure includes several elements:
- aluminum conductor;
- polyethylene screen;
- XLPE insulation jacket;
- two separating layers of glass tape;
- copper wires;
- outer sheath made of PVC.
Each power wire has its own marking. The letter designation "APvVng (A) -LS" means:
- "A" - aluminum conductive core;
- "Pv" - XLPE insulation;
- "B" - the presence of a layer of PVC-compound;
- "ng" - low burning rate;
- "LS" is the minimum amount of gas (smoke) emitted during a fire;
- "(A)" - range of combustion propagation.
Applications
Due to its excellent performance parameters, the APvVng (A) -LS power cable is used in various conditions and branches of human life. The wires are suitable for transmitting current with different rated voltages: 1, 6, 10, 20, 35 kV.
Based on the fact that the weight and cross-sectional diameters of the APvVng (A) -LS power wire is less than that of other cables, it can be laid in:
- dry ground;
- ground space with vertical slopes;
- areas with a high level of flammability;
- underground tanks with flammable mixtures;
- workshops and industrial premises where water hydrolysis is carried out.
The cable is widely used in refrigeration plants and charging stations to power storage batteries. The product can be operated at temperatures ranging from -50 to +50 degrees. Laying the wire is allowed at a temperature of at least -15 degrees.
