How to choose a safe and suitable cable, you know after reading!
Due to the variety of cable specifications, performance is different, so in the selection to fully consider the environmental conditions, laying methods, electrical equipment requirements and product technical data, how to choose a safe and appropriate cable?
一 choose according to the use:
Power cables can be selected for transmission and distribution of electrical energy;
Communication cables can be selected for the transmission of telephone, telegraph, fax documents, television and radio programs, data and other electrical signals
For industrial and mining enterprises, energy and transportation departments, for AC rated voltage 450/750 volts below control, protection lines and other occasions can be selected control cable.
二 according to the laying conditions to choose:
If armored cables can be selected in areas vulnerable to mechanical damage and erosion, the mechanical protective layer can increase the mechanical strength of the cable and improve the anti-erosion ability;
If used in high drop and vertical laying occasions, plastic insulated cables with simple manufacturing, light weight, simple laying and easy maintenance can be selected;
if in the presence of corrosive gases or objects in the environment can choose anti-corrosion cable.
三 Choose according to different security:
1 flame retardant cable can limit the combustion in a local scope, does not produce spread, keep other various equipment, to avoid greater losses, mainly used in hotels, banks, hospitals, factories, commercial and residential wiring and other high flame retardant requirements occasions;
2. Fire-resistant cable can still maintain normal operation for a period of time after accidentally burning, suitable for environments with high safety factor, such as nuclear power plants, subways, tunnels, etc., even if there is an unfortunate fire, it can be constantly powered, which is easy to rescue;
3. The sheath material of low-smoke halogen-free cable does not contain halogen substances, in the case of combustion, does not release halogenated gas, low smoke concentration, most of them are used in places with strict environmental health requirements, it is a very environmentally friendly cable.
