Product Details

Scope of application:

It is suitable for the laying of power equipment, household electrical appliances, instruments and telecommunications equipment with AC rated voltage U0/U of 450/750 and below. Mainly used in places with high safety and environmental protection requirements. Such as high-rise buildings, stations, subways, airports, hospitals, large libraries, stadiums, villas, family houses, hotels, hospitals, office buildings, schools, shopping malls and other crowded places.

Features:

The material of the low-smoke halogen-free wire does not contain any toxic substances such as halogen, and in the case of burning, there is no wire with a large amount of smoke. When a fire occurs, the spread speed is slow, the smoke concentration is low, the visibility is high, and the amount of harmful gas released is small, which is convenient for personnel to evacuate. The combustion gas is less corrosive and avoids damage to the equipment. The low-halogen and halogen-free properties make the cable material greatly resistant to aging and UV and other radiation, thus prolonging the service life of the cable.

Low-smoke, halogen-free wires are made of rubber materials that do not contain halogens (F, Cl, Br, I, At), and do not contain lead, cadmium, mercury, mercury, etc., and do not emit toxic fumes when burned (eg hydrogen halide, Carbon monoxide, carbon dioxide, etc., will not cause secondary hazards, and meet the requirements of modern fire safety. The outer diameter of this kind of wire is smaller than the outer diameter of the whole PVC insulated wire of the same specification cross section. In the pipe construction, the pipe diameter can be reduced, or more wires can be worn under the same pipe diameter, and the construction installation cost can be reduced. . In addition, the wire product is much lighter than the PVC insulated wire product, which is easier to install and transport, reduce labor intensity and reduce transportation costs.

XLPE insulated wires can be rated up to 90 °C for long-term operation and up to 250 °C for short-circuit (maximum duration of 5S). The current carrying capacity is greater than that of PVC insulated wires. The minimum operating temperature of the cable is -15 °C, and the minimum bending diameter is not less than the following: single-core cable: 20D (mm); multi-core cable: 15D (mm) (D: actual outer diameter of the cable).

Low-smoke, halogen-free wires have the following eight characteristics:

(1) Tensile strength is larger than general PVC wire: general PVC wire tensile strength is greater than 1.05Kgf/mm2, while low-smoke halogen-free wire tensile strength is greater than 1.2Kgf/mm2;

(2) Has good weatherability (-30 ° C ~ 105 ° C);

(3) It has non-shifting property (because there is no plasticizer added in the formulation of this product, there will be no shape shifting);

(5) No toxic black smoke will be produced when burning (a small amount of white smoke will be produced);

(5) It has a high volume resistivity: PVC wire is generally 1012~1015Ω/cm3, and low-smoke halogen-free wire is more than 1016Ω/cm3;

(6) Has good high pressure resistance: PVC wire is generally resistant to 10KV or more, and low-smoke halogen-free wire is up to 15KV or more;

According to different performance, low-smoke halogen-free wires can be divided into three types: ordinary, flame-retardant and fire-resistant.

Different models have different product characteristics and there are some differences in terms of use.
