What is the connection between the wires of the PVC?
Note that the PVC wire pipe construction, avoid damage to wall cracks and wall structure caused by the chisel, as the wire in the tube number changes should be laid down, a tube of not more than four, suggested lighting the way to go, air conditioning socket go one way, walk three ~ four road, once a short hair line or other problems, does not affect the normal operation of the other way.
PVC wire tube (Amazon plastic) by type, light, medium and heavy specifications, mainly 16.20.25.32.40.50.PVC wire tube is good or bad, mainly look at features:1., insulation performance is good: PVC electrician bushing insulation good, high resistance to current breakdown voltage, can withstand 25 thousand volts voltage without breakdown, so PVC electrical bushings no live danger.2., strong impact resistance: PVC electrical bushings can withstand the pressure, can be concealed in the concrete, not afraid of compression, impact damage.3., fire resistance performance is good: PVC electrician bushing oxygen index is high, with flammability, leave the flame instantly extinguished.4. moisture-proof, acid and alkali: PVC electric sleeve moisture-proof, not like metal casing corrosion, and acid, alkali, oil resistance.5. insect proof mouse: PVC electric bushing will not send out the smell of insect mouse, and can avoid the bite and bite of insect mice.6. easy to bend: just insert a spring in the pipe, without heating, gently bend with the hand.7., connection way: use adhesive, direct pipe and various parts connection, can complete all kinds of wiring requirements.
According to PVC wire varieties are divided into hard tube, semi hard tube and bellows, according to the characteristics of the line is divided into light, medium, heavy, ultra heavy, according to the wire temperature classification is divided into 25, 05, 90/-25 and so on. The nominal outer diameter specifications of PVC wire tubes are: Phi 16, Phi 20, Phi 25, Phi 32, Phi 40, Phi 50, Phi 63, Phi 75, Phi 110. Among them, PVC pipe specifications for phi 16 and phi 20, generally used for indoor lighting line; PVC tube diameter is Phi 25 specifications, commonly used in the socket or indoor main pipe; PVC pipe diameter is Phi 32 commonly used in the specification into the family line pipe, also for weak line pipe PVC pipe diameter; Specification for phi 50, Phi 63, Phi 75 commonly used in electric disc to indoor line pipe.
