Supply electric cable, cross-linked electric cable, YJV, JVP
This product is suitable for fixed electrical power transmission and distribution lines with AC 50HZ and rated voltage below 35KV. Compared with PVC electric cable
, this product not only has excellent electrical properties, mechanical properties, heat aging resistance, environmental stress resistance, and chemical corrosion resistance, but also has a simple structure and lightweight, and is not limited by the application drop. Long-term working temperature is high (90 °C) and so on.
I. Implementation standards: GB/T12706-2002 is equivalent to the International Electrotechnical Commission IEC60502.
Second, technical parameters:
2.1 The general test method for insulation and sheathing materials of electric cable shall be carried out in accordance with the relevant provisions of GB/T 2951.1~GB/T2951.10;
2.2 Flame-retardant electric cable should meet the requirements of GB/T18380-2001 flame retardant characteristics;
2.3electric cable surface should have a clear manufacturer's name, model, meter and voltage level continuous mark;
2.4electric cable surface without damage, electric cable head tight;
2.5 Packaging, labeling, transportation, storage, and release: According to GB/T133384-92 "General technical conditions for mechanical and electrical product packaging" and other relevant standards.
Third, the use of features:
1. The ambient temperature at the time of laying shall not be lower than 0 °C, and the drop of the electric cable shall not be restricted;
2. The minimum bending radius of the electric cable
is as follows:
Single core: 20 (d + D) ± 5%, three core: 15 (D + d) ± 5% (where D is the actual outer diameter of the electric cable, d is the actual outer diameter of the conductor);
3, the operating temperature of the electric cable:
The PVC sheath is not more than 90 ° C;
4, the highest rated temperature of the electric cable conductor is 90 ° C, when a short circuit (the longest duration does not exceed 5 seconds), the temperature does not exceed 250 ° C
