Wire and cable is often used in electric power at present. The use of wire and cable ensures the laying of relevant power distribution environment. Of course, there are many matters needing attention in the process of power consumption. What are the rubber insulated wire and cable series? Let’s learn more about it together.
First, rubber insulated wire and cable classification.
Rubber insulated wire and cable variety, according to its use can be summarized into ten series, each series includes several varieties.
(1) General-purpose rubber insulated wires. Including rubber insulated wire, rubber insulated cord, etc.
(2) Special rubber insulated wires. Including motor, electrical lead wire, automobile, tractor high voltage ignition wire, etc.
(3) Ordinary rubber-sheathed flexible cables. Including general-purpose rubber-sheathed flexible cables, rubber-sheathed flexible cables for electric welding machines, cables for elevators, cables for radio devices, cables for rolling stock, cables for subway vehicles, rubber-insulated cables for field use, rubber-insulated cold-resistant rubber-sheathed cables, etc.
(4) Mine wires and cables. Including mine mobile rubber flexible cable, mining machine with rubber flexible cable, electric drill cable, mine communication cable, miner’s cap lamp wire, etc.
(5) Marine cables. Including marine power cable
(VI) Rubber insulated power cable
(VII) Rubber insulated control cable
(VIII) Petroleum and geological exploration cables
(IX) DC high voltage cable
(10) Other special-purpose cables, including rubber-sheathed cables and floating water cables used in tropical areas.
Second, commonly used rubber insulated wire and cable model, specification, structure, characteristics and use
(I) Rubber insulated wire
rubber insulated wires are widely used in electrical equipment and lighting equipment. The rated AC voltage is 500V, the long-term working temperature of the conductive wire core is 65 degrees, and most of them are fixed laying. Models BX,BLX (copper and aluminum wire core rubber wire),BXR (copper conductive wire core rubber cord), the cross section range is 0.75-630 mm², the conductive wire core is 1-4 cores, and the basic structure of the wire is conductor, rubber insulation, cotton or glass yarn woven wax. There are also BXF,BLXF type copper-aluminum conductive wire core chloroprene cloth wire, which has a relatively simple structure and is only coated with a layer of chloroprene rubber outside the conductor. Its sunlight resistance, flame resistance and abrasion resistance are improved, and cotton yarn and natural rubber can be saved.
(II) Lead wire of motor and electric appliance
the lead wire of the motor is used to lead the connection wire of the winding. Because this line is to be soaked and dried together with the motor winding and iron core, the lead wire is required to be soft, oil-resistant, solvent-resistant and heat-resistant. Its cross-section range is 0.03-120 mm², and the conductor is tinned copper stranded wire.
(III) Universal Rubber-sheathed Flexible Cable
such cables are widely used to connect household appliances, power tools, various mobile equipment and their power lines. Its structure is copper conductive wire core, rubber insulation, rubber sheath. The ground wire is generally yellow-green double-color line. The W-type derived cable has weather resistance and a certain degree of oil resistance. Suitable for use outdoors or in contact with oil. Heavy-duty cables can withstand large mechanical forces.
(IV) Rubber-sheathed flexible cable for mine
mine rubber sheathed flexible cable is suitable for mine underground mobile electrical equipment and mining machinery supporting copper conductive core rubber insulated rubber sheathed flexible cable. It is required to be soft and resistant to bending, and have a certain mechanical strength and ozone resistance. Type P also has Shielding Requirements. The model specifications of mine rubber sheathed flexible cables include U,UZ,UP,UC,UCP,UG,UGF,UYP,UCP,UGPJ, etc. This type of cable allows long-term working temperature of 65 degrees.
(V) Marine power cables
marine power cables are suitable for ships and floating buildings with rated voltages of AC 500V and below or DC 1000V and below, rubber and PVC plastic insulated cables for power, lighting and general control devices. There are many types of cables, which require moisture resistance, heat resistance, oil resistance and non-ignition performance and certain mechanical strength, and some also require anti-electric wave interference and magnetic interference, according to the different insulating materials, rubber insulated marine cables can be divided into three categories:
1. Natural-Styrene Butadiene Rubber insulated marine power cable, model CF, marine natural Styrene Butadiene Rubber insulated neoprene rubber sheathed cable. CFR, marine natural Styrene Butadiene Rubber insulated neoprene sheathed flexible cable. CV, marine natural Styrene Butadiene Rubber insulated PVC plastic sheathed cable. CY31, marine natural styrene-butadiene rubber insulated nitrile-butadiene polyvinyl chloride composite sheathed steel wire braided cable, etc., the insulation working temperature is 70 degrees.
2. Butyl rubber insulated marine power cable. Model has CDF, Marine butyl rubber insulated heat-resistant neoprene sheathed cable. CDYH32, Marine butyl rubber insulated chlorosulfonated polyethylene sheathed copper wire braided cable, etc., the insulation working temperature is 80 degrees.
3. EPDM rubber insulated marine power cable. Model has CEF, Marine Ethylene Propylene Rubber insulated heat-resistant neoprene rubber sheathed cable. CEYH, Marine EPDM rubber insulated chlorosulfonated polyethylene plastic sheathed cable. CEFR, Marine Ethylene Propylene Rubber insulation heat resistant neoprene rubber sheath flexible cable, etc. The insulation working temperature is 85 degrees.
The above is the specific introduction of the rubber insulated wire and cable series that we bring to you. The rubber insulated wire and cable is a very important power protection unit, which ensures the safety in the power environment.
