Description of fire-resistant wire and cable
Fire-resistant wire and cable refers to a cable that can maintain normal operating characteristics for a certain period of time under specified test conditions, according to the standard requirements of GB/T19216-2008 "Cable or Optical Cable Line Integrity Test under Flame Conditions" , Fire-resistant wires and cables must be burned at 750°C for 90 minutes, and the 2A fuse will not blow.
fire-resistant wire and cable use high-temperature resistant organic flame-proof tape as the fire-resistant layer. According to GB/T19666-2005, fire-resistant wires and cables can be divided into flame-retardant and fire-resistant wires and cables and non-flame-retardant and fire-resistant wires and cables. Flame-retardant and fire-resistant wires and cables mainly include flame retardants in the insulation or sheath, which can simultaneously meet the flame retardant characteristics. Non-flame-retardant fire-resistant wires and cables do not add flame-retardant in the insulation or sheath. It does not have flame-retardant properties.Flame retardant grade

Single-core steel ribbon cable is only suitable for DC system.
Insulated core identification: flame-retardant and fire-resistant power cables are separated according to the requirements of plastic insulated power cable insulation cores, and flame-retardant and fire-resistant control cables are separated according to the identification requirements of plastic insulated control cables. Fire-resistant wires and cables are color-separated according to the identification requirements of plastic insulated wires and cables.
Main performance
The fire resistance of the finished wire and cable is that it burns for 90 minutes under a flame of 750℃ and does not break down under the rated voltage. The test device for its fire resistance characteristics should comply with GB/T19216.11-2003 and IEC60331-11:1999, and the test procedures and requirements for fire resistance characteristics should comply with GB/T19216.21-2003 and IEC60331-21:1999
The flame-retardant properties of the finished flame-retardant and fire-resistant wire should be able to withstand 5 cycles of vertical burning test without transmitting flame. After the test, the continuous burning time of the sample should not exceed 1h. The finished cable should be subjected to a bundled cable burning test. After the test, the height of the scorched or affected part of the cable should not exceed 2.5m above the point of action of the flame.
Wire and cable should withstand -15℃ low temperature winding test or low temperature impact test. After the test, there should be no visible cracks on the surface of the sample.
70℃ finished wire insulation volume resistivity should be greater than 1*1010Ω•cm.
The finished flame-retardant and fire-resistant wire should be able to withstand the 2.5KV AC voltage test without breakdown in 5 minutes. The finished flame-retardant and fire-resistant control cable should be able to withstand the 3KV AC voltage test without breakdown in 5 minutes. The finished flame-retardant and fire-resistant power cable should be able to withstand the 3.5KV AC voltage test without breakdown within 5 minutes
Flame-retardant and fire-resistant wires and cables are made of highly flame-retardant polyvinyl chloride plastic, with an oxygen index greater than 30%
Except for the above characteristics, other performances are the same as those of the same kind of ordinary cables.Key points for selecting fire-resistant cables
In the event of a fire, the wire core resistance increases due to the dramatic increase in ambient temperature. When the flame temperature is 800-1000℃, the conductor resistance increases by about 3-4 times. At this time, the system should still be guaranteed to work normally , Must check the voltage loss under this condition . Generally, it is enough to enlarge the selected wire and cable cross section under normal conditions (ie voltage deviation allowable value +5%~-5%) by one to two levels. Originally, when 50mm2 and below were selected, the first-level cross-section was enlarged, and when it was more than 70mm2, the second-level cross-section was enlarged.
The difference between high temperature resistant cables and fire resistant cables should be distinguished
Generally organic fire-resistant cables are not flame-retardant. If both fire-resistant and flame-retardant requirements are required, flame-retardant and fire-resistant cables or mineral insulated cables should be used.
Ordinary cables and fire-resistant cables are laid in the fire-resistant cable trough box, which may not meet the fire-resistant requirements. -

Delivery length
ZN-BV, ZN-BVV, ZN-BVR and other types of cables (wires) have a loop length of 100 meters, and the coil length should not be less than 100 meters. Short cables with a length of not less than 20 meters are allowed to be delivered, and the quantity should not be less than More than 10% of the total delivery length.
The delivery length of ZN-VV, ZN-VV22, ZN-YJV, ZN-YJV22 cables should not be less than 100m, and the measurement error should not be greater than 0.5%. It is allowed to deliver short cables with a length of not less than 20 meters. The quantity should not exceed 10% of the total delivery length.
The delivery length of fire-resistant control cables such as ZN-KVV, ZN-KVV22, ZN-KVVP2, ZN-KYJV, ZN-KYJV22, ZN-KYJVP2 should not be less than 100m, and the measurement error should not be greater than 0.5%. Allowable length Delivery of short-segment cables less than 20 meters should not exceed 10% of the total length of delivery. 4. According to the agreement between the two parties, delivery of cables of any length is allowed.Packaging signs and transportation
The cable should be properly packaged on a cable reel for delivery. The length of the cable extension should not be less than 300mm, and the end should be reliably sealed with a cable jacket.
A product quality certificate should be attached to each cable package. The certificate should be placed in an impermeable bag and fixed on the side of the cable reel.
The outside of each cable reel should be marked:
Length m Manufacturing Date: Year Month
standard number
Gross weight kg:
A symbol indicating the correct direction of rotation of the cable reel
Transportation and storage
Spools are not allowed to lay flat
During transportation, it is strictly forbidden to drop the cable reel with cables from a height, and it is strictly forbidden to damage the cables mechanically.
When hoisting packages, it is strictly forbidden to hoist several trays at the same time. On vehicles, ships and other transportation tools, the cable reel must be placed firmly and fixed with a suitable method to prevent mutual collision or overturning.
