Description

Efficient flame-retardant electric special wire

Technical Field

The invention relates to the technical field of electrical equipment, in particular to an efficient flame-retardant electric special wire.

Background

The cable consists of one or more insulated wires and a tough outer layer made of metal or rubber. Cables and wires are generally composed of three components, a core, an insulating sheath and a protective sheath. The common cable has the characteristics of a CEF-ethylene propylene rubber insulating chloroprene rubber sheath and a marine flame-retardant power cable. CVV-polyvinyl chloride insulation, polyvinyl chloride sheath marine flame retardant power cable. BV, BX, RV and RVV series wires are commonly adopted as the oxygen chamber wires, wherein the BV-copper core polyvinyl chloride insulated wires are fixedly laid indoors and outdoors at the allowable temperature of 65 ℃ for a long time, the lowest temperature is-15 ℃, the working voltage is 500V for alternating current and 1000V for direct current, and the wires can be laid in the open or the dark. BX-copper core rubber insulated wire, the maximum service temperature is 65 ℃, and the wire is coated indoors. RV-polyvinyl chloride insulation single core flexible wire, the maximum service temperature is 65 ℃, the minimum service temperature is-15 ℃, the working voltage is 250V of alternating current, the direct current is 500V, and the single core flexible wire is used as the internal wiring of instruments and equipment. RVV- -copper core polyvinyl chloride insulation and sheath flexible wire, allows long-term working temperature to be 105 ℃, working voltage to be 500V alternating current and 1000V direct current, and is used for occasions with humidity, high mechanical protection requirements and frequent movement and bending. In fact, "wires" and "cables" are not strictly limited. The product with less cores, small product diameter and simple structure is generally called wire, the product without insulation is called bare wire, the other product is called cable, the product with larger conductor cross section area (more than 6 square millimeters) is called large wire, the product with smaller conductor cross section area (less than or equal to 6 square millimeters) is called small wire, the insulated wire is called distributing wire, so the insulated wire is simpler, it is easy to understand that!cable generally has more than 2 layers of insulation, most of the multi-core structure is wound on a cable reel, and the length is generally more than 100 meters. The wire is typically a single layer insulation, single core, 100 meter roll, wireless disc. The common model of the cable is VV, namely polyvinyl chloride insulation (first V), a polyvinyl chloride sheath (second V) YJV22, namely cross-linked polyvinyl chloride insulation (YJ), a polyvinyl chloride sheath (V), and a steel belt armour (22) with the model of ZR or FR, which is a flame-retardant cable (wire). The type of the wire with the L is simpler, and the wire with the L is BVV-polyvinyl chloride insulation and sheath copper core wire, BV-polyvinyl chloride insulation copper core wire, BYJ-copper core cross-linked polyolefin insulation wire, BVR-polyvinyl chloride insulation copper core flexible wire, BX-rubber insulation copper core wire and RHF-neoprene sheath copper core flexible wire. However, the conventional electric wire has low fire-proof capability.

Therefore, a high-efficiency flame-retardant electric wire special for electricity needs to be researched.
