Fire-resistant cables are suitable for high-rise buildings, oil fields, power stations, power plants, mines, chemical industry, mines, subway and other occasions requiring high fire protection conditions. They are also the standby cables for emergency power supply, fire pump and elevator communication signal system. This product has the fire-resistant ability of fire-resistant cables and does not occur in a certain period of time (not less than 3 hours) under the condition of direct flame combustion. Short-circuit and Break-circuit failures ensure that power supply is maintained to maintain lighting and transmit signals, to protect personnel from evacuation in sufficient time, and to facilitate fire extinguishing and reduce losses.

Conductor: high purity oxygen-free bare copper wire.Thermal Insulation Layer: High Temperature Resistant Synthetic MicaInsulation: high flame retardant polyvinyl chloride insulator at 70 CTwo or more layers of mica tapes are used to overlap the outer conductor. Generally, the overlap rate is not less than 30%. Sometimes, the overlap rate reaches 50% to meet the requirements of the fire resistance test, so as to achieve the fire resistance test as the benchmark. The winding angle is controlled at 40-50 degrees.

●The flame retardant properties of flame retardant cables (wires) should be tested by bundles of wires and cables GB1266.5-90 and IEC 332-3. The flame retardant grades can be divided into four categories: A, B, C and D.
●The fire resistance of refractory cables (wires) shall pass the fire resistance tests specified in GB1266.5-90 and IEC 331.
●Physical and mechanical properties: the tensile strength of insulation is not less than 10.0 MPa, the elongation at break is not less than 100%; the tensile strength of sheath is not less than 12.0 MPa, and the elongation at break is not less than 100%.
●Minimum bending radius: (Series B) The allowable bending radius should be no less than 4D if the cable outer diameter (D) is less than 25MM; and the allowable bending radius should be no less than 6D if the cable outer diameter (D) is more than 25MM.
●Operating voltage: U。/U爲450/750、300/500、300/300V
●Test voltage: 2000V
●Long-term allowable temperature of cable: - 105 type cable allowable working temperature should not exceed 105 other types of cable allowable working temperature should not exceed 70.
●The laying temperature of the cable should not be less than 0 C. -
●The structure of fire-resistant wire and cable is different from that of flame-retardant wire and cable. It can be burned for a long time or even after burning, even if the polymer material in the flame is burnt down, the cable can ensure the normal operation of the line for more than hours.
●It has the characteristics of acid and alkali resistance, oil resistance, moisture-proof and mildew-proof.
● ROHSenvironmental protection
●Wire has high flame retardancy, strong self-extinguishing property and extinguishing characteristic when it leaves fire. -
