The classification and use of Rubber insulated wire and cable
Rubber insulated wire and cable, with various kinds, which can be summarized as the top ten series by use:
(1) general rubber insulated wire. Including rubber insulated wire, rubber insulated cord and so on.
(2) special rubber insulated wire. Including motor, electrical wiring, cars, tractors, such as high-pressure ignition line.
(3) Ordinary rubber sheathed flexible cable. Including general rubber flexible cable, soft rubber cable for welding machine, cable for elevator, cable for radio equipment, cable for locomotive and vehicle, cable for subway vehicle, rubber insulated cable for field and rubber insulated cold-resistant rubber sheathed cable.
(4) Mine wire and cable. Including mining mobile rubber sheathed flexible cable, mining equipment with rubber flexible cable, electric drill cable, mine communication cable, miners cap lights line.
(5) marine cables. Including marine power cables
(6) rubber insulated power cable
(7) rubber insulated control cable
(8) oil and geological exploration cable
(9) DC high voltage cable
(10) other special purpose cables, including tropical rubber cables, water cables and so on.
And here are the models, specifications, structure, characteristics and uses of common rubber insulated wire and cable:
(1) rubber insulated wire is widely used in electrical equipment and lighting equipment, AC rated voltage of 500 volts, conductive core long-term working temperature of 65 degrees, the majority of fixed laying, model BX, BLX, BXR , cross-section range of 0.75-630 square millimeters, conductive core for the 1-4 core, the basic structure of the wire is the conductor, rubber insulation, cotton yarn or glass wool woven wax.
(2) The connection line of motor and electric appliance, is used to lead the winding connection. Because this line to be with the motor winding and iron impregnated with the drying, so the requirements of the wiring to be soft, oil, solvent, heat. Its cross-section range of 0.03-120 square millimeters, the conductor with tinned copper wire.
(3) General rubber flexible cable is widely used to connect household appliances, power tools, all kinds of mobile equipment and power lines. Its structure is copper conductive wire core, rubber insulation, rubber sheath. Ground line generally use yellow and green color line. The W-type derived cable is resistant to weather and certain oil resistance. Suitable for outdoor or contact with the use of oil occasions. Heavy-duty cable can withstand greater mechanical external force.
(4) Mine rubber sheathed flexible cable is suitable for mine underground mobile electrical equipment and mining machinery supporting copper conductive wire core rubber insulated rubber sheathed flexible cable. Requiring soft and resistant to bending, and have a certain degree of mechanical strength and ozone resistance. P-type also have shielding requirements, mining rubber flexible cable models specifications U, UZ, UP, UC, UCP, UG, UGF, UYP, UCP, UGPJ and so on. This type of cable is allowed to operate at a temperature of 65℃ for a long time.
(5) Marine power cables are suitable for rubber and PVC plastic insulated cables for dynamic, lighting and general control devices with rated voltages of 500 volts or less and 1000 volts or less in ships and floating buildings. Type cable type more, requires a moisture, heat, oil and non-flame performance and a certain degree of mechanical strength, and some also require anti-radio interference and magnetic interference.
