Source : Tianxing Cable | Release date : 2024-04-30
WDZN-RYJS -- Copper core low smoke halogen-free flame retardant crosslinked polyolefin insulated twisted connection flexible wire

1. Product use

WDZN-RYJS wire and cable is fire-fighting refractory polyolefin insulated connection flexible wire is formulated with reference to GB/T5023-2008, and its fire resistance characteristics meet the requirements of GB/Tl9666 class. Widely used in instrumentation, aerospace, electric power smelting, chemical industry, ships, vehicles, food machinery, household appliances and so on.

2. Scope of use

WDZN-RYJS fire-resistant polyolefin insulated connection flexible wire suitable for power plants. Chemicals, tunnels, stations. The fire prevention system of high-rise buildings and other key parts is especially suitable for emergency power supply and indoor fire equipment power supply lines. This product is suitable for lines with rated AC voltage of 450/750V and below, and the occasions with high fire safety requirements. With high flame retardant and fire resistance, in the case of repeated direct flame burning, there is no short circuit and open circuit fault in a certain period of time, so in the case of fire, it is conducive to fire fighting and reducing losses. The power supply line of the emergency power supply and fire alarm equipment, the power supply line of the emergency power supply to the signal lamp, and the power supply line of the emergency power supply to the ventilation and smoke exhaust equipment.

Three, cable characteristics

(1) halogen-free acid gas is released.

(2) Less smoke.

(3) Less corrosive gas is produced.

(4) Good flame retardant performance.

4. Conditions of use

(1) Rated AC voltage U0/U is 450/750V and below;

(2) The long-term working temperature of the wire conductor does not exceed halogen +70℃;

(3) Short-circuit temperature should not exceed 160℃(duration 5S);

(4) When the cable is laid, the ambient temperature is not lower than 0℃, and the bending radius: if the outer diameter (D) of the cable is less than 25mm, the bending radius should not be less than (4D); if the outer diameter (D) of the cable is 25mm and above, the bending radius should not be less than 6D;

(5) Flame retardant characteristics: in line with GB/T 19666-2005 provisions.
