• The cable conductor allows a long-term operating temperature of 90 ° C, the maximum temperature of the cable conductor does not exceed 250 ° C during short circuit, and the duration does not exceed 5 seconds.
• The ambient temperature when laying the cable should not be lower than 0 °C.
· Allowable bending radius for cable laying:
— cable without armor should be no less than 6 times the diameter of the cable
— Cables with armor or copper tape shielding results should be no less than 12 times the cable diameter
— Flexible cables with a shield structure should be no less than 6 times the diameter of the cable.
• When the conductor is allowed to operate at a temperature of not more than 90 ° C for a long time, the identification life of the cable is not less than 40 years.
· The finished cable should meet the requirements of Class A bundled burning test specified in GB/T18380.3.
· Finished cable smoke density: light transmittance is not less than 70%.
· Radiation resistance: 25 × 104Gy
• Halogen-free: When the non-metallic material is burned, the acidity of the evolved gas (expressed as PH value) should be greater than 4.3; the conductivity is not more than 10 μS/mm.
Bare wire and bare conductor products
The main features of this product are: pure conductor metal, no insulation and sheath layer, such as steel core aluminum stranded wire, copper-aluminum busbar, electric locomotive line, etc.; processing technology is mainly pressure processing, such as smelting, rolling, pulling System, stranding/tightening stranding, etc.; products are mainly used in suburbs, rural areas, user main lines, switch cabinets, etc.
The products are mainly used for transmission of strong electric energy in the transmission, distribution, transmission, transformation and power supply lines. The current passing through is large (tens of amps to several thousand amps) and the voltage is high (220V to 500kV and above).
Communication cable and fiber
With the rapid development of the communication industry in the past two decades, the products have also experienced phenomenal growth. From the simple telephone telegraph cable of the past to thousands of pairs of cable, coaxial cable, optical cable, data cable, and even combined communication cable. The structural dimensions of such products are generally small and uniform, and manufacturing precision is required.
Electromagnetic wire (winding wire)
Mainly used in various motors, instrumentation, etc.
Flexible fireproof cable
1, excellent fire performance, fire resistance not only meets the international GB12666.6A class 950 °C 90min can also meet the requirements of British BS6387-1994 A grade 650 ° C 3h B grade 750 ° C 3h C grade 950 ° C 3h requirements can also resist in the combustion Subject to water spray and mechanical impact.
2, continuous length is long whether the single-core or multi-core cable can meet the length of the power supply, the limit length can reach 2000m.
3, the cross section of the large single core cable section up to 1000mm2 multi-core cable section up to 240mm2.
4, flexible, cable can be on the cable tray, its bending radius ≥ 20D, D is the cable outer diameter.
5. Smokeless and non-toxic when burning, the insulation adopts inorganic material “non-burning body”, it will not produce any harmful gas when burning, and it will not cause secondary pollution. It is called environmentally friendly green product.
6. The cross-section capability is too large, and the cable not only has a large cross-sectional flow but also has a large overload capacity. According to the wiring requirements, the cable surface temperature is usually ≤70 °C? If the wiring is not touchable or in contact with combustible building materials, the cable sheath temperature can reach 105 °C. The fireproof cable allows an operating temperature of up to 250 °C during overload.
7, corrosion-resistant, organic insulated fire-resistant cables sometimes need to wear plastic tubes or iron pipes, plastics are easy to age and become brittle, iron pipes are easy to rust; fire-resistant cables are copper sheaths do not need to wear pipes, copper sheaths have good corrosion resistance.
8. No electromagnetic interference, fireproof cable and signal, control and other wires and cables are laid in the same shaft. The fireproof cable is shielded by the copper sheath. It will not interfere with the information transmitted by the signal and control wire and cable.
9. The safety is good. In addition to the normal power supply in the flame, the fireproof cable starts the fire extinguishing equipment to reduce the fire damage. At the same time, it is also particularly reliable for personal safety. Its copper sheath is a good conductor, it is the best grounding wire, and it continues to the full length of the cable, which greatly improves the sensitivity and reliability of grounding protection.
10, long service life, inorganic insulating materials, high temperature resistance, and not easy to age, his life is many times higher than organic insulated cables? Under normal working conditions, its life can be equivalent to buildings.
11. Transportation and installation of flexible fireproof cables includes installation.
The derivative/new products of wire and cable are mainly for applications and applications.
To meet the requirements of different and convenient equipment and reduce equipment costs, and to use new materials, special materials, or to change the product structure, or to improve the process requirements, or to combine different varieties of products.
Use different materials such as: flame retardant cable, low-smoke halogen-free/low-smoke low-halogen cable, termite-proof, mouse-proof cable, oil/cold/temperature resistant cable, etc.
Change product structure such as: fire resistant cable, etc.
Improve process requirements such as: medical cables, etc.
Combination products such as: OPGW, etc.
Easy to install and reduce equipment costs such as: prefabricated branch cables.
The wire and cable products used in the power system mainly include overhead bare wires, bus bars (bus bars), power cables (plastic cables, oil-paper cables (substantially replaced by plastic power cables), rubber cables, overhead insulated cables), and branch cables. (Replaces some busbars), magnet wires, and electrical equipment, wire and cable for power equipment.
The wire and cable used for the information transmission system mainly includes local telephone cable, television cable, electronic cable, radio frequency cable, optical fiber cable, data cable, electromagnetic wire, power communication or other composite cable.
This part is used in almost all other products except for overhead bare wires, but mainly power cables, magnet wires, data cables, instrumentation cables, etc.
