Wire and cable classification and product details

1, bare wire and bare conductor products only conductor without any insulation layer is called bare wire and bare conductor products 1.1 Bare single wire Non-ferrous metal round wire, flat wire, tinned wire, bimetallic wire 1.2 Bare stranded wire Mainly used as an overhead conductor Insulation relies on the external arrangement, the conductor itself is not divided into voltage levels! There are mainly aluminum stranded wire, copper stranded wire, aluminum alloy stranded wire and so on. Occupies more than 90% of the length of the entire power grid line main models: LGJ LJ TJ LGJF LJX, etc. 1.3 flexible wires and braided wires refers to a very thin single-wire bundle stranded, compound stranded or braided made of very soft wires, the conductor all with copper. Such as brush wires, battery cables, etc. 1.4 Type wires and profiles Bare conductive products that are not round. 1 Copper and aluminum rows 2 Contact network wires 3 Various shaped rows

2, power cable conductor with high-quality insulation structure, and a good protective layer of cable. The main function and overhead wires, the same as in the power system for transmission and distribution of large-capacity electrical energy, the difference is that power cables can be laid in a variety of occasions, safe and hidden, not subject to external climatic disturbances, can be less maintenance, durability, high cost, power cables have the following characteristics: 1 can withstand higher, very high operating voltage, with excellent electrical insulation properties 2 can transmit a very large amount of current (hundreds of amps, Thousands of amps) should have good heat resistance and heat dissipation 3 requires laying in a variety of environments, so there are a variety of structures to protect the sheath. 4 Due to the capacity of the power system, the voltage, the number of phases of the different and the laying environment of the changes in the power system so that the power system varieties, specifications are quite a lot of classification of power cables are mainly classified according to the insulation structure, the insulation material is categorized in accordance with the provisions of the electric power system, China's power cables of the rated voltage class Divided into: 1 KV and below (known as low-voltage) 3kv, 6kV, 10kV, (15kV, 20kV, 30kVv), 35kV (6-35kV known as the medium voltage, the voltage level within the parentheses, the domestic generally do not use) 66kV, 110kV, 220kV, 330kV (66-330kV known as high-voltage) 500kV (500kV and above known as) 500kV (500kV and above is called ultra-high voltage, 750kV and above is called ultra-high voltage) for the neutral point of the different grounding methods, the standard provides for medium and low voltage power cables in the voltage level series are: 0.6/1, 1.8/3, 3/3, 3.6/6, 6/6, 6/10, 8.7/10, 8.7/15, 12/20, 18/20, 18/30, 21/35, 26/35, 64 /110 The unit is kilovolt Commonly used power cable cores are 1, 2, 3, 4, 5 cores. Only low-voltage power cables using 4, 5-core, low-voltage cable for the user network, shall be equipped with neutral and direct grounding core. Cable conductor cross-section specifications are: 2.5 4 6 10 16 25 35 50 70 95 120 150 185 240 300 400 500 630 800 1000 unit for the square millimeter 3, electrical equipment with the widest range of wires and cables, the most varieties, large production 3.1 general-purpose insulated wires, cords, the main models: BV BLV BVR BVV BLVV BV- 105 BLV-105 BVR-105 BVR-105 BVR-105 BVR- 105 BLV-105 BVR-105 BVR-105 BVR-105 BVR-105 105 BLV-105 BVR-105 RV RVB RVS RVV BX BLX BXR, etc. 3.2 General rubber cable main models: light rubber cable YQ YQW medium-sized rubber cable YZ YZW heavy rubber cable YC YCW3.3 counting, signaling and control wires and cables for this type of cable, the main consideration of the high-temperature characteristics and shielding properties and oil resistance, acid and alkali resistance, Water-resistant properties of the main models: KVV KVVP KVVP2 KVV22 KVV32 KVVR KVVRP (if the insulating material is changed from PVC to XLPE, it becomes another series) 3.4 Marine wire and cable for ships and floating buildings on the water of the electric power, lighting, signaling, control and communication links with the special products. Insulation materials used are mainly polyvinyl chloride, natural rubber, ethylene-propylene rubber, silicone rubber, cross-linked polyethylene jacket: polyvinyl chloride, chloroprene rubber and chlorine (sulfonated) polyethylene 3.5 Extraction wires and cables (mining rubber soft cables) The main models are: UC-0.38/0.66 UCP-0.38/0.66 UCP-0.66/1.14 UY-0.38/0.66 UYP-0.38/0.66 UYP-0.66/1.143.6 cable accessories: refers to wire and cable products in the composition of the system line must be connected to the intermediate or terminal connection device and its corresponding supporting devices. Cable accessories are independent products, quite important. Line about 80% of the accident occurred in the cable body and accessories of the connection, so the quality of accessories and installation process is particularly important. MT 818.XX-1999 stipulates that the coal mine cable in the cable before the general type plus M4 electromagnetic wire (winding wire) and communication fiber optic cables 4.1 Electromagnetic wire 1) Enameled wire The use of coated enamel and high-temperature baking process. Round ones are used for small and medium-sized motors and instruments; flat ones are used for large motors and transformers.2) Winding wire Winding paper tape, film, cotton yarn, synthetic filaments and alkali-free glass filaments, dipped and coated with bonding varnish and dried, mostly used for large transformers.4.2 Communication fiber-optic cables refer to communication cables, fiber-optic cables, and electronic cables; electronic cables are also known as RF cables all of which belong to the wired transmission and are good at keeping confidentiality and not easily affected by the climate and the electromagnetic wave interference. Servo cables: Yaskawa servo cable, Omron servo line, Mitsubishi servo cable, Panasonic servo cable, Delta servo cable oil-resistant PVC jacket makes the cable especially suitable for industrial applications The maximum length of the cable is in line with the manufacturer's servomotor use regulations Our cable has been verified by millions of uninterrupted bending tests to ensure that the product has excellent performance and reliability High temperature, cold, oil and corrosion resistance High brand Our cables are manufactured to high standards for Delta, Panasonic, Mitsubishi, Siemens, Yaskawa, Fuji and other brands.
