RVS Wire Rated Voltage Uo/U:300 / 300 V CU Conductor/ Electrical Wires And Cables Use for Builing and House
Description:
RVS wire is called copper-cored PVC insulated stranded connection use soft wire, pair twisted multi-stranded soft wire, referred to as twisted pair cable, commonly known as "flower wire" in China. At present, this kind of wire is mostly used in fire fighting system, also known as "fire line".
Construction characteristics:
Conductor: stranded flexible copper class 6 ( annealed or tinned)
Insulation:PVC
Electrical characteristics
Rated Voltage Uo/U:300 / 300 V
Standard: JB/T8734.3-2012
Maximum working temperature: +70 °C
Packaging: 100m/roll or as request
Remarks:
Flame retardant, fire resistance (adopt mica tape), low smoking and Halogen free, or other property are available.
ZR cable (flame retardant cable) is the kind of cable with PVC insulation built mixed with fire prevention additive to make it have the capability of preventing or retarding flame spread during combustion.
There are 3 grades of fire prevention available which are
Grade A It is the highest level of flame retardancy. That is, the insulation material, filling rope, fastening (inner cushion) belt/layer and sheath material used in cables are all flame retardant materials.
Grade B Except the insulation material, all other materials are flame retardant.
Grade C Only the sheath material is flame retardant
NH cable(fire resistant cable) is the kind of cable built with a layer of mica tape. Even if the plastic skin is burnt out, refractory layer will help not cause short circuit. When wiring, cut off the refractory layer at the wire head.
LSZH,LSOH,LS0H,LSFH or OHLS cable(Low smoke zero halogen cable)is cable with insulation or outer sheath built using low smoke zero halogen free material to help reduce toxic and corrosive gases produced during combustion.
Termite-proof cable is the cable built with insulation or outer sheath mixed with a kind of materials to prevent termite biting the cable.
