Product Description


This cable is suitable for AC rated voltage U0 / U 450/750 and below the power plant, electric appliances, instrumentation and telecommunications equipment laying.
Be used in safety and environmental protection places. Such as high-rise buildings, railway stations, subways, airports, hospitals, large library, gym, villas, family homes, hotels, hospitals, office buildings, schools, shopping malls and other crowded places.

Cables Features

LSZH cable refers to the halogen-free (F, Cl, Br, I, At), no lead cadmium, chromium and mercury and other environmental substances in plastic material and does not emit toxic fumes (such as during combustion: hydrogen halides, carbon monoxide, carbon dioxide, etc.), no secondary hazards, meet modern fire safety requirements of environmental protection wires. This wire has an outer diameter smaller than the full PVC insulated wire cross-section of the outer diameter of the same size, the construction can be reduced through the use of tube diameter, or wear more wires under the same diameter conditions, reduce the cost of construction and installation. In addition, the wire product weight than PVC insulated wire products are much lighter, easier installation and transportation, reduce labor intensity, reduce transportation costs.
When cross-linked polyethylene insulated wire long-term maximum rated temperature up to 90℃, short (the longest duration of no more than 5S) up to a maximum temperature of conductor wires 250℃, carrying capacity greater than PVC insulated wire. Cable minimum working temperature of -15℃, the minimum bending diameter not less than the following: Single cable: 20D(mm); multi-core cable: 15D(mm) (D: Cable actual diameter).

The following 8 major characteristics of halogen cable:

(1) Tensile strength than PVC wire large: typically PVC wire tensile strength greater than 1.05Kgf / mm², and a tensile strength greater than low-smoke, halogen-free wire 1.2Kgf / mm²;
(2) has a good weather resistance (-30 ℃ ~ 105 ℃);
(3) having a non-metastatic (because this product formulations without the addition of plasticizers, it will not have a transitional character);
(4) does not produce toxic smoke when burned (generates a small amount of white smoke);
(5) has a higher volume resistivity: PVC wire is generally 1012 ~ 1015Ω / cm3, halogen wires than 1016Ω / cm3;
(6) has a good high voltage characteristics: PVC wire generally more resistant to 10KV, 15KV high wire above and halogen;

Depending on the performance of the wire, it can be divided into three models,ordinary halogen, flame retardant, fire.

Different models with different product features, but also some differences in the use.

Models Features Usage
BYJ It has excellent mechanical and physical properties and electrical properties, good resistance to environmental stress cracking resistance, excellent abrasion resistance than PVC and PE.Resistance to various chemical solvents, corrosive media around the relatively stable. AC rated voltage U0 / U 450/750 and below the power plant, electric appliances, instrumentation and telecommunications equipment laying.
WDZ-BYJ Cable with flame retardant, fire ignition delay only limited to a certain range. Also it has a low smoke emission and harmless, very little smoke when burned, non-corrosive gases escape. Suitable for cable flame, smoke density and toxic index places with special requirements.It widely used in nuclear power plants, subway station, telephone exchange and computer control center, building high-rise buildings, hotels, radio and television, important military facilities, oil platforms etc., as well as personnel more focused, low air density places. well as personnel more focused, low air density places.
WDN-BYJ In addition to the power transmission cable under normal operating conditions, while the fire combustion, the cable also can keep running for some time. When in fire, it still maintain the normal operation of the circuit such as industrial and civil construction of fire safety systems, emergency lighting systems, life support systems, alarm and monitoring circuits.


WDN-BYJ cable design, should be used for:

1. fire pumps, spray pumps, fire elevator power lines and control cables.
2. fire shutter doors, electric fire doors, exhaust system fan, exhaust valves, dampers power supply control circuit.
3. manual alarm line fire alarm systems, fire radio and telephone lines.
4. high-rise buildings and airports, subways,CCTV security line and other important facilities.
5. centralized power supply emergency lighting circuits, control and protection of power lines.
6. medium-sized substation important protection circuits and operate power lines.
7. computer monitoring circuit.

Description of fire-resistant wire and cable

Fire-resistant wire and cable refers to the specified test conditions, the flame combustion can be maintained within a certain period of time running cables.
1. according to GB / T19216-2003 "in electric cables under fire conditions - Circuit integrity" of standards, fire-resistant wire and cable must burn 90min at 750 ℃, 2A fuse is not blown.
2. fire-resistant wire and cable with high temperature organic firebreak for refractory layer. According to GB/T19666-2005, fire-resistant wire and cable wire and cable can be divided into fire retardant and non-flame resistant wire and cable. Fire retardant is added to the main wire and cable insulation or sheath flame retardant, it can meet the flame retardant characteristics. Non-fire retardant wire and cable insulation or jacket is not flame retardant, it does not have fire-retardant properties.
3. according to GB / T18380.3-2002 specified test conditions, retardant wire and cable is divided into A, B, C, D four grades.
