List of main types of wires and cables
RV, RVV, RVVP, RVVY, RVVYP, KVVRP, (N)2YSLC, ZR-RE, ZR-REE, ZR-REEP, PUR, LIYY, LIYCY, LIYY(TP), LIYCY(TP), LI2YCY, PIMF, LIHH , LIHCH.
The characteristics of commonly used cables are as follows
CEF——Ethylene-propylene rubber insulated neoprene sheath, flame-retardant power cable for ships
CVV——PVC insulated, PVC sheathed flame-retardant power cable for ships
Oxygen cabin wires often use BV, BX, RV, RVV series wires, of which:
BV-copper core PVC insulated wire, long-term allowable temperature 65℃, minimum temperature -15℃, working voltage AC 500V, DC 1000V, fixedly laid indoors and outdoors, and can be laid in the open or in the dark.
BX——Copper core rubber insulated wire, the highest operating temperature is 65℃, for indoor use.
RV——PVC insulated single-core flexible cord, maximum operating temperature 65℃, minimum operating temperature -15℃, working voltage AC 250V, DC 500V, used as internal wiring of instruments and equipment.
RVV——Copper core PVC insulated and sheathed flexible wire, allowing long-term working temperature of 105℃, working voltage of AC 500V, DC 1000V, used in damp, high mechanical protection requirements, frequent movement and bending occasions.
Common cable models
VV means: PVC insulation (the first V), PVC sheath (the second V)
YJV22 means: cross-linked polyvinyl chloride insulation (YJ), polyvinyl chloride sheath (V), steel tape Kaizhuang (22)
type plus "ZR" or "FR" are flame-retardant cables (wires). Add "L" for aluminum wire
Wire and cable model naming rules
The model of wire is relatively simple:
BVV--PVC insulated and sheathed copper core wire,
BV--PVC insulated copper core wire,
BVR--PVC insulated copper core cord,
BX--rubber insulated copper core wire,
RHF--chloroprene rubber sheathed copper core cord.
