Aluminum Alloy Conductor Cross-Linked Polyethylene Yjlhv Electrical Power Cable Wire

Scope of application
System
This product is suitable for AC 50Hz, rated voltage 0.6/1kV line (system maximum voltage 1.2kV) power line transmission power
Occasion
Laid in metallurgy, electric power, construction and other industries of indoor, cable trench, pipeline, directly buried and can not withstand mechanical external force fixed use occasions
Product characteristics
Aluminum alloy power cable makes up for the shortcomings of pure aluminum cable in the past, although it does not improve the electrical conductivity of the cable, but the bending performance, creep resistance and corrosion resistance are greatly improved, which can ensure that the cable maintains stable performance when overloaded and overheated for a long time.
Compliant standard
Executive standard
GB/T 31840-2015 Rated voltage 1kV(Um=1.2kV) to 35KV (Um= 40.5kV) aluminum alloy core extruded insulated power cable

Identification of product
 Wire core

1. Color marking Multi-core cables with different colors, in accordance with the following provisions: 2-core cables: red, blue; 3-core cable: yellow, green, red; 4 core cable: yellow, green, red, blue; 5-core cable: yellow, green, red, blue, black (or determined by the supply and demand parties); 2. Digital identification Multi-core cable using digital identification, in line with the following provisions: 2-core cable: 0, 1; 3-core cable: 1, 2, 3; 4 core cable: 0, 1, 2, 3; 5-core cable: 0, 1, 2, 3, 4; The numbers 1, 2, and 3 are used for the main core, and 0 is used for the neutral core. In 5-core cables, the number “4” refers to the specific purpose conductor (including the ground conductor), and when the insulated core is digitally identified, the insulation should be the same color and arranged according to the number. Arabic numerals should be printed on the surface of the insulated wire core, and the color of the numerals should be the same and have obvious contrast with the insulation color and the handwriting is clear; The digital signs shall be repeated at equal intervals along the insulated wire core, and the two adjacent sets of digital signs shall be reversed from each other. When the logo is composed of a single number, a dash should be placed under the number, if the logo is composed of two numbers, it should be arranged up and down and placed under the following number, and the spacing d between the two adjacent groups of digital identifies should not be greater than 50mm.

Sheath
The outer sheath of the cable is usually black, but a color other than black can also be used in accordance with the manufacturer or buyer’s agreement to adapt to its use environment. The cable shall have continuous identification of the manufacturer’s name, product model and rated voltage, and the manufacturer’s name identification may be repeated identification of the manufacturer or trademark; The distance between the end of one complete mark and the beginning of the next mark shall not exceed 500mm on the outer sheath of the cable; The cable insulation or tape should not exceed 200mm; The printed logo should be erasable and not fall off, and the printed content on the surface should be legible. Note: The logo on the surface of the sheath can also add other content according to the custom of the user or the manufacturer.
Delivery of goods and the length of the differences
Delivery of  length
Cables weighing less than 80kg are allowed to be delivered in rings, and the delivery length of short sections of the cable shall not exceed 5% of the total length of the delivery, or any length of cable may be delivered according to the agreement between the parties
Error in length
The measurement error of delivery length should not exceed ±0.5%
