Is YJV cable soft? The difference between wires and cables of Zhengzhou yicable Co., Ltd

  　　  Differences between wires and cables of Zhengzhou first cable Co
, Ltd
Differences between wires and cables The wire is composed of one or several soft wires, which are covered with a light and soft protective layer The cable is composed of one or several insulated conductors, which are wrapped with a tough outer layer made of metal or rubber Cables and wires are generally composed of three parts: core wire, insulating sheath and protective sheath The characteristics of common cables are as follows: 　　CEF—& mdash; Ethylene propylene rubber insulation, neoprene sheath, marine flame retardant power cable 　　CVV—& mdash; PVC insulated, PVC sheathed marine flame retardant power cable BV, BX, RV, RVV series wires are often used for oxygen cabin wires, Including: bv & mdash& mdash; Copper core PVC insulated wire, with long-term allowable temperature of 65 ℃, minimum temperature of - 15 ℃, working voltage of AC 500V and DC 1000V, is fixedly laid indoors and outdoors, and can be laid in open or dark 　　BX—& mdash; Copper core rubber insulated wire, with a maximum service temperature of 65 ℃, is applied indoors 　　RV—& mdash; PVC insulated single core flexible wire, with maximum service temperature of 65 ℃, minimum service temperature of - 15 ℃, working voltage of AC 250V and DC 500V, is used as internal wiring of instruments and equipment 　　RVV—& mdash; Copper core PVC insulated and sheathed flexible wire allows long-term working temperature of 105 ℃, working voltage of AC 500V and DC 1000V
It is used in wet, high mechanical protection requirements, and often moving and bending In fact, & ldquo; Wire & rdquo; And & ldquo; Cable & rdquo; There are no strict boundaries Generally, products with few cores, small diameter and simple structure are called wires, those without insulation are called bare wires, and others are called cables The larger conductor cross-sectional area (more than 6 mm2) is called large wire, the smaller one (less than or equal to 6 mm2) is called small wire, and the insulated wire is also called cloth wire
This is relatively simple and easy to understand Cables generally have more than two layers of insulation, most of which are multi-core structure, wound on the cable reel, and the length is generally more than 100m
Wires are generally single-layer insulation, single core, 100 meter roll, wireless disk Common models of cables: VV: PVC insulation (the first V), PVC sheath (the second V) yjv22: cross connected PVC insulation (YJ), PVC sheath (V), steel strip kaizhuang (22) model plus & ldquo; ZR” Or & ldquo; FR” The is flame retardant cable (wire)
Add & ldquo; L” The model of aluminum wire is relatively simple: BVV -- PVC insulated and sheathed copper core wire, BV -- PVC insulated copper core wire, BVR -- PVC insulated copper core wire, BX -- rubber insulated copper core wire, RHF -- neoprene rubber sheathed copper core wire
