6-Wire core identification

6.1 Insulation coloring identification:

6.1.1 When colored insulation is used for identification of insulated wire cores, each insulated wire core may only use one color, except for the green/yellow combination color.

6.1.2 The insulation core colors of any multi-core cable cannot be green and yellow, which are not combined colors.

6.1.2 For green/yellow insulated wire cores, one color shall cover at least 30% and not more than 70% of the surface of the insulated wire core, and the other color shall cover the rest and be consistent throughout.

6.1.4 The preferred color spectrum for insulation coloring of cables with five cores or less is as follows:

1 core and 2 core: no preference for color spectrum;

3 cores: green/yellow, blue, brown or brown, black, gray;

4 cores: green/yellow, brown, black, gray or blue, brown, black, gray;

5-core: green/yellow, blue, brown, black, gray or blue, brown, black, gray, black.

6.1.5 When there are special requirements for chromatography, the supply and demand parties can negotiate and determine according to customer requirements.

6.2 Insulation digital identification:

6.2.1 Cables with six or more cores shall be identified by numbers. The insulation shall be of the same color and arranged numerically in natural order from the inner layer to the outer layer starting with the No. 1 insulated core (black insulation with white lettering is recommended), except for the green/yellow insulated core (if any).

6.2.2 When the sign consists of a single number, a horizontal line should be added under the number. When the sign consists of two numbers, they should be arranged vertically and a horizontal line should be added under the latter number. The interval di between two adjacent groups of numbers should not be greater than 50mm. The arrangement of the digital identification signs is shown in the figure below:

7-Sheath color

White, black or as per customer's requirement

8-Special performance requirements

Flame retardant A/B/C grade, fire resistant, termite resistant, rodent resistant, UV resistant, low temperature resistant, mineral oil resistant, etc.

9- Cable application characteristics

9.1 The maximum long-term rated temperature allowed for the cable conductor during normal operation is 70°C.

9.2 The maximum allowable temperature of the cable conductor during short circuit (duration not exceeding 5 seconds) is 160℃.

9.3 The cable installation temperature should not be lower than 0 ℃

9.4 Minimum bending radius for cable installation:

The minimum bending radius of cables with an outer diameter less than 25 mm : not less than 4 times the outer diameter of the cable;

The minimum bending radius of cables with an outer diameter greater than or equal to 25 mm : not less than 6 times the outer diameter of the cable.

9.5 This series of PVC-insulated wires and cables has a maximum voltage rating of 450/750V and is widely used in residential, commercial, and industrial environments for electric lighting and internal wiring, household appliances, electric equipment, instrumentation, control equipment, electronic equipment, and automatic devices. Installation methods include fixed wiring, indoor or outdoor , or embedded in conduit or similar closed systems.
