Low-smoke halogen-free power cable

It is suitable for use in high-rise buildings, centralized personnel and high environmental protection requirements.

The flame retardant performance is superior, the smoke released during combustion is less, the visibility is high, the amount of harmful gas released is less, and it is convenient for people to evacuate; the corrosiveness of combustion gas is small, and the damage of multi-instrument equipment is avoided.

Low-smoke halogen-free power cable

Product introduction

Low smoke halogen-free wires and cables produce very small amount of smoke under the condition of flame combustion, which releases gas without halogen and non-toxic. When fire occurs, it can greatly reduce the harm to instruments/equipment and human body, so it is widely used in high-rise buildings/hospitals, large libraries, stadiums, Disaster Prevention Command and dispatch buildings, stations and civil airports. Passenger waiting rooms, key cultural relics protection sites and subway, underground shopping malls or densely populated public places.

Our company develops and produces plastic insulated wires and cables with rated voltage of 35KV and below. Their performance not only meets the requirements of GB/T 12766-2008, GB/T 5023-2008 and GB/T 9330-2008, but also forms a series of flame-retardant, fire-resistant, especially low smoke and halogen-free properties, which meet the national standards GB/T 17650-1-2-1998 and GB/T 17651.1-2-1998. At the national level, sci tech novelty searches have reached the domestic advanced level of similar products.

Product technical performance

1. The maximum operating temperature and the maximum short-circuited (no more than 5 seconds) temperature of the wire and cable conductor: 70°Cfor the low-smoke halogen-free PVC insulated cable, with the maximum short-circuited temperature no higher than 160°C; 90°Cfor the XLPE insulated cable, 80°Cfor the thermoplastic low-smoke halogen-free PO insulated cable, with the maximum short-circuited temperature no higher than 250°C; 105°Cand 125°Cfor the irradiated XLPE insulated cable, with the maximum short-circuited temperature no higher than 250°C.

2. The installation conditions and allowable continuous current-carrying capacity of the low-smoke halogen-free cable are the same as that of the non-low-smoke halogen-free cable.
3. The cable and wire have low-smoke, halogen-free, flame-retarding and fireproof properties when burning, with specific indicators as shown in the following figure.

Serial number	Test project	Standard requirements
1	Single vertical burning test of wire and cable - Distance between the lower edge of upper bracket and the starting point of carbonized part - the distance that the combustion extends downward to the lower edge of the upper bracket	≥50mm ≤540mm
2	Standard requirements	≤2.5m
3	Fire resistance test	When burning for 90 min, apply the rated voltage and find that the 2A fuse is not fused
4	PH value	≥4.3
5	Weighted value of conductivity	≤10µs/mm
6	Cable smoke density test - the minimum light transmittance	≤60%
