Occasion
Fixed laying in metallurgy, electric power, construction and other industries indoors, cable trenches, pipelines, direct burial and other places that do not need to withstand mechanical external force.
Product Characteristics
The raw materials for product production are widely sourced and cheap, and are easy to process and manufacture.
The product is insulated with cross-linked polyethylene. Compared with PVC insulated cables, it has better insulation performance and canwithstand extremely high working temperatures, up to 90 degrees.
The product is armored with steel tape and can withstand greater mechanical pressure.
The standard
Executive standard
GB/T 12706.1-2020 Extruded insulated power cables and accessories with rated voltage 1kV (Um=1.2kV) to 35kV (Um=40.5kV) Part 1: Rated voltage 1kV (Um=1.2kV) and 3kV (Um=3.6kV ) )cable
additional standards
Using features
Rated voltage
The rated voltage is 0.6/1kV, and the maximum voltage of the AC system should not exceed 1.2kV.
Operating temperature
The maximum allowable long-term operating temperature of the cable conductor is 90°C; In the case of short circuit, the maximum temperature of the cable conductor shall not exceed 250 ° C and the duration shall not exceed 5s.
ambient temperature
The minimum ambient temperature for cable operation is -15ºC.
Laying temperature
When installing and laying, the temperature should not be lower than 0ºC.
bending radius
The bending radius of single-core cables should be no less than 20 times the outer diameter of the cable, and the bending radius of multi-core cables should be no less than 15 times the outer diameter of the cable.
Product Identification
Core of cable
1.Color identification When multi-core cables are marked with different colors, they must comply with the following regulations: 2-core cable: red, blue; 3-core cable: yellow, green, red; 4-core cable: yellow, green, red, blue; 5-core cable Cable: yellow, green, red, blue, black (or determined by negotiation between the supplier and the buyer). The colors red, yellow and green are used for the main wire core. Blue is used for the neutral core. In order to avoid confusion with other colors, it is recommended to use light blue.
2. Digital identification When multi-core cables use digital identification, they must comply with the following regulations: 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 a 5-core cable, the number “4” refers to the specific purpose conductor (including the grounding conductor). When the insulated cores are marked with numbers, the insulation should be of the same color and arranged according to the numbers. Numbers should be printed on the surface of the insulated core with Arabic numerals. The color of the numbers should be the same and have obvious contrast with the insulation color and the writing should be clear; the number signs should be repeated at equal intervals along the insulated core, and two adjacent sets of number signs should be Invert each other. When the logo consists of a single number, a dash should be placed below the number. If the The logo consists of two numbers, it should be arranged up and down and a dash should be placed below the subsequent numbers. The spacing between two adjacent sets of digital logos is d. Should be no larger than 50mm.
Sheath
The outer sheath of the cable is usually black, but it can also be in colors other than black according to the manufacturer or buyer’s agreement to adapt to its use environment. The cable should have continuous identification of the manufacturer’s name, product model and rated voltage . The manufacturer’s name identification can be Duplicate identification of manufacturer or trademark. The printed logo should be scratch-resistant and not fall off, and the printed content on the surface should be clearly legible. Note: The logo on the surface of the sheath can also add other logo contents according to the habits of the user or manufacturer.
Delivery and Tolerance
Delivery Length
Cables weighing less than 80kg are allowed to be delivered in coils, and the delivery length of short-segment cables should not exceed 5% of the total delivery length, or cables of any length can be delivered according to mutual agreement.
Delivery and Tolerance
Delivery length measurement error is ±0.5%
