Low smoke halogen free cable
Description
1. Features and Uses: low-smoke halogen-free cable products are suitable for subway, high-rise buildings, shopping malls, theaters, power stations, chemical factories, city squares and other public utilities with rated AC voltage of 450/750V and below where the flame-retardant characteristics of cables are highly required. The characteristics of halogen free and low smoke, low halogen and low smoke, when the fire occurs, the spread speed is slow, the smoke concentration is low, the visibility is high, the release of harmful gas is small, easy to evacuate personnel. The corrosion of combustion gas is small, but also to avoid damage to instruments and equipment, low halogen, halogen free characteristics, so that the cable material in aging resistance and UV resistance and other radiation performance is greatly extended, thus extending the use of cable. Two, product implementation standard: GB9330-88Q/WTL11-2003 Three, use characteristics: 1. Cable rated voltage UO/U:450/750V, AC polyolefin UO/U is 0.6/1KV 2. Long-term working temperature of cable :-20℃-90℃, -40℃-105℃ 3. Bending radius: not less than 6 times of the outer diameter of unarmored cables, and not less than 12 times of the outer diameter of cables with armored or copper tape shielding structure. Four, the main indicators: 1. The cable should withstand the power frequency voltage test at the ambient temperature of 3kV, 5min no breakdown 2. The transmittance of the cable should comply with the following table
| Cable outer diameter D(mm) | Transmittance (%)≥ | Cable outer diameter D(mm) | Transmittance (%)≥ |
| D > 40 | 70 | 5 < D≤10 | 50 |
| 10 < D≤40 | 60 | D 5 or more | 40 |
3. Cable non-delay flammability (flame retardant characteristics): should pass GB12666.5-90 class B bunch-burning test. Single wire and cable vertical combustion test should pass GB12666.2-90 4. 5. The PH value and conductivity of the combustion gas are 754-2 pH ≥4.3 conductivity ≤10μS/mm. V. Basic Model and Name:
