Low smoke halogen free cable
Categories :
Description :
Low halogen low smoke characteristics, when the fire occurs, the spread speed is slow, low smoke concentration, high visibility, small amount of harmful gas release, easy to evacuate personnel. The corrosion of combustion gas is small, and the damage to equipment is also avoided. The characteristics of low halogen and halogen free make the cable material have great aging resistance and uv resistance and other irradiation resistance, so as to prolong the use of the cable. Product execution standard: GB9330-88Q/WTL11-2003 Rated cable voltage UO/U:450/750V, AC polyolefin UO/U is 0.6/1kV 2. The long-term working temperature of the cable is -20℃-90℃, -40℃-105℃ 3. Bending radius: no less than 6 times of cable diameter for unarmored cables, no less than 12 times of cable diameter for armored or copper belt shielded cables. 1. The cable shall be subjected to power frequency voltage test of 3kV under ambient temperature and shall not break down in 5min. 2. The transmittance of cables should comply with the following table
| Outer diameter of cable D(mm) | Transmittance (%)≥ | Outer diameter of cable D(mm) | Transmittance (%)≥ |
| D > 40 | 70 | 5 < D 10 or less | 50 |
| 10 < D 40 or less | 60 | D 5 or more | 40 |
3. Non-flame retardant cable (flame retardant characteristics): should pass gb12666.5-90 class B bundle combustion test. Single wire and cable vertical combustion test shall pass GB12666.2-904. PH value and conductivity of combustion gas, 754-2pH ≥4.3 conductivity ≤10μS/mm. V. Basic Model and Name:
