Introduction: First, the product features and uses, PVC and sheath control cable for AC rated voltage Uo / U is 450/750V and below the control and monitoring circuit and protection circuit and other occasions, as the control wiring between electrical equipment.
The main characteristic of the flame-retardant control cable is that the cable is not easy to ignite or the fire retards when the fire is only limited within a certain range, and it is suitable for the occasion with high requirements for the flame retardant performance.
The main characteristic of the fire-resistant control cable is that in addition to being able to transmit power under normal working conditions, the cable can maintain normal operation for a certain period of time when it ignites and burns, and is suitable for occasions where fire resistance characteristics are required.
Second, the product standard This product is organized according to GB9330-1988 standard production, but also according to user requirements of other standards.
In addition to the flame-retardant cable according to the above standards, its flame retardant performance is divided into three different flame-retardant categories A, B, and C according to the provisions of GB/T 18380.3-2001, and the flame retardant performance of the A-class category is optimal. According to the need to use.
The fire-resistance performance of fire-resisting cables should conform to GB/T 19216.21-2003
Third, the product model Ordinary cable type KVV-copper core PVC insulated PVC sheathed control cable KVVP-copper core PVC insulated PVC sheathed braided shielded control cable KVVP2-copper core PVC insulated polychlorinated Ethylene sheathed copper tape shielded control cable KVV22 - copper core PVC insulated PVC sheathed steel tape armored control cable KVV32 - copper core PVC insulated PVC sheathed thin steel wire armored control cable KVVP2-22- Cu core PVC insulated PVC sheathed Cu tape shielded steel tape armored control cable KVVR - copper core PVC insulated PVC sheathed control flexible cable KVVRP - copper core PVC insulated PVC sheathed braided Shielded control flexible cable flame-retardant cable model plus ZA, ZB, ZC in front of common control cable model
Fire-resistant cable models add N to common control cable models
Fourth, product use characteristics 1. The rated voltage Uo/U is 450/750V.
2. The long-term allowable working temperature of the cable conductor is 70°C.
3. The laying temperature of the cable should not be lower than 0°C. The recommended allowable bending radius is as follows:
Unshielded cables should not be less than 6 times the outer diameter of the cable.
Cables with armoured or copper tape shielded construction shall be not less than 12 times the outside diameter of the cable.
The flexible cable with a shield structure should not be less than 6 times the outer diameter of the cable.
