Ten specific things to keep in mind about cable installation

Wire and cable is a general term for items such as fiber optic cables and cables. There are many uses of cables, mainly used to control the installation, connecting equipment, transmission of electricity and other multiple roles, is a common and indispensable thing in daily life. Because the cable is electrified, so the installation needs to be especially careful. 1, 6kv and above cable joints. a, when installing the cable terminal head, must be stripped of the semi-conductive shielding layer, the operation shall not damage the insulation, should avoid the knife marks and unevenness of the situation, if necessary, to be smoothed with sandpaper; shielding should be leveled at the end, and the graphite layer (carbon particles) to be removed cleanly. b, plastic-insulated cable termination of the copper shielding and steel armour must be well Grounding, the short line should also follow this principle, to avoid three-phase unbalanced operation of steel armor ends produce induced electromotive force, and even "fire" and burning sheath and other accidents. c. Three-phase copper shielding should be connected to the ground respectively, pay attention to the shielding ground line and steel armor ground line should be led out separately, insulated from each other, the position of the welding ground line should be as far down as possible. 2, on the end of the cable and intermediate connectors Basic requirements: a. Conductor connection is good; b. Reliable insulation, recommended irradiated crosslinking heat-shrinkable silicone rubber insulation; c. Good sealing; d. Sufficient mechanical strength to adapt to a variety of operating conditions. 3, cable ends must be waterproof, as well as other corrosive materials, to prevent breakdown due to the aging of the insulation layer caused by the tree of water. 4, cable loading and unloading must be the use of a crane or forklift, prohibit Flat transport, flat put, large cable installation must be used to release the cable car, so as to avoid damage to the cable by external forces or due to manual dragging and scratches on the insulation layer. 5, the cable can not be laid in a timely manner for any reason, it should be placed in a dry place for storage, to prevent exposure to sunlight, the cable end of the water and so on. 6, mining cables and heat pipes should be installed in parallel with the heat pipe should be maintained at a distance of 2m, should be maintained at a distance of 0.5m when the cross. 7, cables and other pipeline Parallel or cross installation should be kept at a distance of 0.5m. 8, cable direct burial installation, 1-35kV cable direct burial depth should be not less than 0.7m. 9, 10kV and the following cables are installed in parallel with each other net distance of not less than 0.1m, 10-35kV is not less than 0.25m, the distance between the cross is not less than 0.5m. 10, the minimum bending radius of the cable, multi-core cables shall not be less than 15D, single-core cable shall not be less than 20D (D is the outer diameter of the cable). Specializing in the production of 35KV and the following high and low voltage power cables, rubber cables, mining cables, control cables, steel stranded aluminum stranded wire, aluminum stranded wire and environmentally friendly low-smoke halogen-free cables, fire-retardant cables, aluminum alloy cables and other 300 categories of up to more than 6,000 kinds of wire and cable products.
