Production execution standards

Enterprise standard and refer to British Standard BS5308.

Use characteristics

1. Rated voltage UO/U is 300/500V; long-term working temperature of cable conductor: polyvinyl chloride has 70C and 105℃; polyethylene insulation is 70℃; cross-linked polyethylene insulation is 90℃ (insulation cross-linked type Can be divided into silane crosslinking and irradiation crosslinking).

2. The cable can be used for fixed laying under the condition of ambient temperature -40℃~50℃, and the ambient temperature should not be lower than 0℃ during laying.

3. For cables with copper tape shielding structure, the bending radius should not be less than 10 times the outer diameter of the cable when laying; the bending radius should not be less than 12 times the outer diameter of the cable when laying the armored cable; the bending radius when laying other cables should be Not less than 6 times the outer diameter of the cable

Note: The conductor structure of the computer cable is generally made of Type A or Type R. If users need products with Type B conductor structure, please indicate in the contract when ordering.

2. Insulation resistance: PVC insulation resistance

3. The cable should withstand the power frequency AC voltage test; test voltage: 2000V, test time is 5min, test temperature is ambient temperature

	Nominal cross section of conductor
