450 / 750V Insulated RV Building Wire / Nominal section area: 1*1.5~1*70mm²/Conductor: flexible conductor class 5
RV Building Wire Application:
RV cable is widely used in industrial distribution field. It is especially suitable for flexible installation places with stricter requirements, such as electronic control cabinets, distribution boxes and various low-voltage electrical equipment. It can be used for transmission of power, electrical control signals and switching signals. RV wire and cable are designed with soft structure. The bending radius of conductor is small, and it is suitable for wet and oily installation places.
RV Building Wire Construction characteristics
Conductor: flexible conductor class 5 (China GB/T 3956 class 5 or
IEC60228 class 5)
Insulation: PVC
Rated voltage and standard:
300/500V 60227 IEC06 or GB/T5023.3-2008
450/750V 60227 IEC02 or GB/T5023.3-2008
Minimum service temperature: - 30 C
Maximum service temperature available +70 °C, +90 °C, +105 °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.
