High voltage cable is a kind of power cable. It refers to the power cable used to transmit 1kv-1000kv. It is mostly used for power transmission and distribution. The product is suitable for fixed lines of power supply, transmission and distribution with AC rated voltage of 35kV and below. The maximum long-term working temperature of cable conductor is 90 degrees. In case of short circuit (the maximum time does not exceed 5S), the maximum temperature of cable conductor does not exceed 250 degrees.
Compared with low-voltage overhead lines and low-voltage overhead insulated lines, although the cost is higher and the laying and maintenance is more difficult, low-voltage cable lines are widely used in low-voltage distribution systems because they have the characteristics of reliable operation, no pole, no occupation of the ground, no obstruction to the view and less affected by the outside world.
This product is applicable to household appliances, electric tools and various mobile electrical equipment with rated voltage of 750V and below. It is produced according to GB / t5013-2008 rubber insulated cables with rated voltage of 300 / 500V; 450 / 750V and below and jb18735-2016 rubber insulated flexible wires and cables with rated voltage of 450 / 750V and below.
The product is applicable to the power connection of gantry crane, elevator and trailer equipment moving at a low speed below 20m / min. The product shall be wound, retracted and released on the same plane, and no turning is allowed in the retraction and release line. The product is applicable to the connection of control censer of driving equipment and the connection between control cabinet and button box. It is not applicable to the occasion of towing. Long term allowable working temperature of cable core: - 15p-50p. The product shall not bear any mechanical stress other than its own weight during use.
Fireproof series cables are very suitable for high-rise residential buildings, commercial buildings, public buildings (such as hospitals, schools and exhibition halls), metallurgy, chemical industry, rail transit, nuclear power plants, military industry, high-temperature flammable and explosive places and other fields with high fire safety requirements
Control cables are PVC insulated and PVC sheathed control cables suitable for industrial and mining enterprises, energy and transportation departments, control and protection lines with AC rated voltage below 450 / 750 V.
This product is in accordance with national standards GB / t19666-2005 and GB / T12706 1-2008 or IEC 502-1994. The product is applicable to transmission and distribution lines with AC rated voltage of 0.6/1kv and below.
Low smoke halogen-free cable is the material classification of wire sheath in wire and cable industry. The low smoke halogen-free wire sheath is composed of thermoplastic or thermosetting materials with low smoke emission when heated and free of halogen. For example, in the railway industry or shipbuilding industry, a very important demand is to protect personnel and equipment from toxic and corrosive gases. In these occasions, it is required to use low smoke and halogen-free materials for the outer layer of wires and cables.
It is used for power devices, household appliances, small electric tools, instruments and power lighting lines with AC rated voltage of UO / u and 450 / 750V and below. Uo - effective value of voltage between any insulated conductor and "ground" (metal shield or surrounding medium). U - effective value of voltage between any two-phase conductors of multi-core cable or single core cable system.
The products are used for underground roadway lighting in coal mines, conveyor interlocking and control, and power connection with signal equipment. The long-term allowable working temperature of the cable is 65 ℃. In case of short circuit (the maximum duration is no more than 5S), the maximum temperature of the cable conductor is no more than 150 ^ 0. The minimum bending radius of the cable is 6 times of the outer diameter of the cable.
It is used for connecting cables of photovoltaic power generation system, such as parallel cables between strings and between strings and DC distribution box (combiner box), series cables between photovoltaic modules on DC side, cross-linked cables between strings and between strings and DC distribution box (combiner box), and cables between DC distribution box and inverter. It can also be used for AC application cables for connection between inverter and transmission network.
secondary side-welding of welding machine or connecting electrode holder.
The company has become a technology-intensive and eficient economic entity engaged in the research and development, production and operation of wire and cable high-tech and its products.
