Fire wire is the fire line of the emergency lighting or alarm system with the wire, different wire uses and characteristics are different, naturally match different electrical and instrument systems, Qingdao cable manufacturers to introduce the fire wire commonly used models.

Fire service wire

1) RVV, RVVP: copper core PVC insulated PVC sheathed soft wire/shielded soft wire, mostly used for electrical appliances, meters to connect power lines, transmission lines; RVVP has shielding properties to resist external signal interference.

2) BV, BLV: PVC insulated wire. Same as BX type, but better moisture resistance and weather resistance.

3) BVR: PVC insulated soft wire. Same as BV type, only used where soft installation is required.

4) BVV, BLVV: PVC insulated and sheathed wires. With the BV type, it is used in places with high humidity and mechanical protection requirements, and can be directly buried in the soil.

5) BV-105, BLV-105: Heat resistant 105℃ polyneon-ethylene insulated wire with type B, used in 45℃ and above high temperature environment.

6) BVR-105: Heat resistant 105℃ PVC insulated soft wire. Same as BVR type, used in 45℃ and above high temperature environment.

7) RV: single core copper core vinyl chloride insulated cord. For all kinds of mobile electrical appliances, meters, telecommunications equipment, automation equipment wiring; It is also used as a wire for internal installation, and the ambient temperature during installation is not lower than -15℃.

8) RVB: two-core flat copper core polyvinyl chloride insulated flexible wire. For all kinds of mobile electrical appliances, meters, telecommunications equipment, automation equipment wiring; It is also used as a wire for internal installation, and the ambient temperature during installation is not lower than -15℃.

9) RVS: two-core copper core polyvinyl chloride stranded connection cord. For all kinds of mobile electrical appliances, meters, telecommunications equipment, automation equipment wiring; It is also used for internal installation, and the ambient temperature during installation is not less than 15 ° C. Places with high requirements and frequent movement and bending.

10) AVR; Tinned copper core PVC insulated flat connection flexible wire.

11) RV-105: Copper core heat resistant 1050C PVC insulated PVC insulated connection flexible wire.

The above are commonly used wire models for fire protection, and different models are suitable for different fire protection facilities and environments. In the purchase, you need to choose the right wire model according to the actual demand.
