Wire and cable expertise - rubber insulated wire and cable basics

May 23,2018

Wire and cable refers to materials used for power, communications, and related transmission purposes. "Wire" and "cable" do not have strict boundaries. Usually, the product with a small number of cores, a small product diameter, and a simple structure is called a wire. A wire without insulation is called a bare wire. Others are called cables. A conductor with a larger cross-sectional area (greater than 6 mm2) is called a large wire. Small (less than or equal to 6 mm2) is called a small wire, and an insulated wire is also called a cloth wire.

Henan Sanheng Industrial Co., Ltd. introduced the basic knowledge of rubber insulated wire and cable:

(A) Rubber insulated wire Rubber insulated wire is widely used in electrical equipment and lighting equipment, AC rated voltage of 500 volts, conductive wire core long-term working temperature of 65 degrees, mostly fixed laying, model BX, BLX (copper, aluminum wire core Rubber wire), BXR (copper conductive core rubber cord), cross-sectional range of 0.75-630 square millimeters, conductive core 1-4 core, the basic structure of the wire is a conductor, rubber insulation, cotton yarn or glass wire braided wax. There are BXF, BLXF type copper and aluminum conductive core cordoprene wire, the structure is relatively simple, only a layer of neoprene rubber coating on the outside of the conductor, its resistance to sunlight, fire resistance, resistance to rubbing is improved, and can save cotton yarn and natural glue.

(B) motor, electrical lead wire electrical motor lead wire is used to connect the winding of the cable. Because this type of wire is to be impregnated and baked along with the motor windings and the core, it is required that the lead wire be flexible, oil-resistant, solvent-resistant, and heat-resistant. Its cross-section range is 0.03-120 square millimeters and the conductor is tinned copper wire.

(C) General purpose rubber sheathed flexible cable This type of cable is widely used to connect household appliances, power tools, various mobile devices and their power lines. Its structure is copper conductive core, rubber insulation, rubber sheath. Ground lines generally use yellow-green two-color lines. The W-derived cable has weather resistance and a certain degree of oil resistance. Suitable for outdoor use or contact with oil. Heavy-duty cables can withstand large external mechanical forces.

(4) Mining rubber sheathed flexible cables Mine rubber sheathed flexible cables are used for underground mobile electrical equipment and mining machinery supporting copper conductive core rubber insulated rubber sheathed flexible cables. It requires softness and bending resistance, and has certain mechanical strength and ozone resistance. P-type also has shielding requirements, mine rubber flexible cable model specifications U, UZ, UP, UC, UCP, UG, UGF, UYP, UCP, UGPJ and so on. This type of cable allows long-term operating temperature of 65 degrees.

(E) Marine Power Cables Marine power cables are suitable for use in ships and floating structures on water, rated at voltages up to 500 V AC and below or DC 1000 V or below for power, lighting and rubber and PVC insulation for general control devices. Cables, these cable types are more, require moisture resistance, heat resistance, oil resistance and non-flammability and a certain degree of mechanical strength, and some also require anti-electrical interference and magnetic interference, according to the different insulation materials.

Henan Sanheng Industrial Co., Ltd. , founded in 2000, It is one of the top wire and cable manufacturers in China's wire and cable industry for nearly 20 years. the company has more than 5 production lines.

The production cable can be divided into more than 50 varieties and subdivided into 1000 specifications.All products have passed national certification, such as China compulsory certification, bv certification, Nigerian SONCAP certificate, China national industrial certification, etc. China national industrial production license, etc.It also has the ability to produce products that meet international standards, such as iec, ce, rohs, etc.
If you want to buy wires and cables, you can ask the customer service staff and we will get back to you as soon as possible.
