The types uses of cables are also different, the selection of cables is also different. What cable options are available?Guangxi cable manufacturer

Because halogen-containing flame-retardant cables (including flame-retardant cables, low-halogen low-smoke flame-retardant cables) will release corrosive halogen acid gas when burning, which greatly hinders the fire-fighting work, delays the fire-fighting time, aggravates the spread of the fire. High-density public places should try to design halogen-free low-smoke flame-retardant cables. Any type of flame retardant cable can be used in low density work areas.

It is impossible to distinguish A, B, C flame retardant cables the appearance. Only the manufacturer guarantees supply. Remind everyone to choose the cable manufacturer carefully when purchasing, you can ask to participate in providing relevant information.

Compared with halogen-containing flame-retardant cables, halogen-free low-smoke flame-retardant cables have the advantages of low corrosion low smoke, but their electrical mechanical properties are significantly reduced. When laying cables, halogen-free low-smoke flame-retardant cables should contain more halogen flame-retardant cables have a larger bending radius.

When designing cable laying, non-flame retardant cables flame retardant cables should be laid side by side, flame retardant cables of different flame retardant categories should be laid side by side.

Specific methods of cable maintenance

Cables are important communication equipment require maintenance during normal use for their safe operation. Cables need maintenance in daily production life. What are the specific maintenance methods?Guangxi wire cable

If the rubber sheathed cable is broken the copper wire of the core wire is broken more than 15%, it is necessary to reconnect the core wire by cold pressing, remove the burr of the crimping tube, carry out insulation treatment vulcanization heat repair.

In addition to vulcanization hot repair, cold repair repairs can be performed if cable damage is found. At the same time, maintenance work must ensure the use of non-combustible materials.

At the same time, when repairing the rubber sheathed cable, semiconductor shielding metal mesh shielding must be done to ensure the shielding function, a shielding test should be carried out. If interrupt shielding occurs, first find the disconnection point, then carry out targeted repair work. Guangxi cable
