Detailed description

WDZ-KEJYP 3*2.5 green environmental protection low smoke halogen-free flame retardant control cable

WDZ-KEJYP-450/750 Rated voltage 450/750V irradiation cross-linked low smoke halogen-free flame retardant polyolefin insulation and sheath copper wire braided shielding green environmental protection halogen-free low smoke flame retardant control cable

1. Scope of application

Green environmental protection low smoke halogen-free flame retardant cable has excellent flame retardant performance, very little smoke during combustion, no corrosive gas escape, widely used in nuclear power plants, subway stations, tunnels, telephone exchanges and computer control centers, high-rise buildings, hotels, radio and television stations, hospitals, theaters, power stations, important military facilities, oil platforms, etc., as well as places with concentrated personnel and low air density.

2. Green environmental protection low smoke halogen-free flame retardant cable use characteristics

The rated power frequency voltage U0/U is: 0.6/1kV for power cable; 450/750V for control cable; 300/500V for computer cable

The maximum allowable operating temperature of the cable conductor is: 90℃, 105℃, 125℃, 150℃ respectively.

When the cable is short-circuited (the longest duration does not exceed 5s), the maximum temperature of the cable conductor does not exceed: 250℃

Cable bending radius: power cable should not be less than 20 times the outer diameter of the cable; control cable 12 times; computer cable 12 times

Ambient temperature during cable laying: ≥0℃ (if it must be laid in an environment below 0℃, the cable should be preheated to above 0℃ before laying)

Technical characteristics of green environmental protection low smoke halogen-free flame retardant cable

Excellent flame retardancy and non-flammability.

The amount of smoke generated during combustion is very small, no toxic gas is generated, and no corrosive gas is generated.

It has good mechanical and physical properties and electrical properties, and can meet the use requirements of the cable.

It does not contain heavy metals and does not pollute the soil.

The cable’s temperature resistance level is improved; the current carrying capacity is increased.
