Cable Gland Should Pay Attention To What Matters
Cable Gland, also known as cable head. After the cable is laid, in order to make it a continuous line, the segments must be connected as a whole, and these connections are called cable gland. Cable cable in the middle of the Cable Gland called the middle connector, and the two ends of the Cable Gland called the terminal head.
Cable Gland according to the installation of the premises can be divided into indoor and outdoor two.
According to the production of materials can be divided into heat shrinkable (the most commonly used), dry bag and epoxy resin pouring and cold shrink.
According to the core material can be divided into copper power cable head and aluminum core power cable head.
According to the connector material is divided into plastic Cable Gland and metal Cable Gland. Metal Cable Gland is divided into porous metal cable waterproof connector, anti-bending metal Cable Gland, double locking metal cable waterproof connector, plastic hose Cable Gland, metal hose Cable Gland. Its main function is to make the line smooth, so that the cable to keep sealed, and to ensure that the Cable Gland at the insulation level, so that safe and reliable operation. If the seal is not good, not only will oil leakage caused by oil and paper dry, and moisture will penetrate the cable inside, so that paper insulation performance
The Cable Gland material quality is also uneven, but in order to ensure the quality of cable joints, it is recommended not to seek cheap, the best choice of quality reliable Cable Gland manufacturers of materials! In order to ensure the quality of the Cable Gland,
Second: the Cable Gland is best not to choose rainy days, because the cable water will seriously affect the service life of the cable, serious or even a short circuit accident!
Third: Before making the Cable Gland must carefully read the manufacturer's product brochures, which for 10kV and above cable, is particularly important! Do all the processes before you want to do again!
Fourth: more than 10kV single-core armored cable terminal fittings, remember that only one end of the steel belt to ground!
Fifth: copper tube can not be pressed too hard, as long as the pressure in place can be! After the pressure of the copper side is bound to have a lot of raised points, this must use the file level, can not leave any glitches!
Sixth: heat-shrinkable Cable Gland in the use of torch, pay attention to the torch to move back and forth, not only in the direction of a continuous fire!
Seventh: cold shrink Cable Gland size must be strictly in accordance with the instructions to do, especially when the support of the tube in the support, but also be careful!
