This product complies with GB/T 19666 and GB/T 12706 standards, and has the highest flame retardant properties It can meet the requirements of Category A in GB/T 18380.3. The light transmittance and HCl corrosive gas release when burning low-smoke halogen-free cables meet the standard requirements.
Usage Features
When halogen-free and low-smoke cables are used normally, the long-term allowable operating temperature of the conductor is 90°C. When short-circuited (maximum short-circuit time 5s), the maximum conductor temperature does not exceed 250°C.
When low-smoke and low-halogen cables are used normally, the long-term allowable operating temperature of the conductor does not exceed 70°C. When short-circuited (maximum short-circuit time 5S), the maximum conductor temperature does not exceed 160°C.
The minimum temperature for cable laying is 0°C, and the minimum bending radius during laying: without armor layer, should be no less than 8 times the outer diameter of the cable. When armored, it should be no less than 12 times the outer diameter of the cable.
Model and name

Note: Corresponding fire-resistant cables can be produced according to user requirements.
Four cores can be divided into four cores with equal cross-sections or three large and one small unequal cross-section structures; five cores can be divided into three large and two small or four large and one small unequal cross-section structures; the color can be provided according to the user's color code.
Technical indicators

The finished cable insulation resistance, the insulation resistance constant when converted to 20℃ should not be less than 36.7M&Omega ;·km.
The finished cable should withstand the withstand voltage test of AC 50Hz  3.5kV test voltage. The test stability lasts for 5 minutes without breakdown.
Smoke density test when burning halogen-free low-smoke flame-retardant cables, the minimum transmittance is not less than 60%. The release amount of hydrogen chloride gas (HCL) is not more than 5%, the pH value is not less than 4.3, and the conductivity is not more than 10μs/mm.
In the smoke density test when burning low-smoke and low-halogen flame-retardant cables, the minimum light transmittance is not less than 35%, and the hydrogen chloride gas release is not more than 100mg/g.
Delivery length
Power cables are generally delivered in reels. The total delivery length is generally not less than 100m. Short sections of cables with a length of not less than 20m are allowed to be delivered. But its quantity should not exceed 10% of the total delivery volume. According to the agreement between the two sides, delivery can be made in any length, with a length measurement error of ±0.5%.
