Electrical design in the basement of sewage treatment cable to wear waterproof casing, waterproof casing to use what type
Is the filler: cable cable core is a number of insulated wire stranded in the process of forming a cable will inevitably produce gaps, if these gaps do not fill the material with dense, cable cable core instability, reduce the cable in the The use of the process of life, two in the cable when the jacket, the cable sheathing material will be embedded in the middle of the cable core, resulting in cable costs rise. The role of filler is: to ensure that the cable round, to avoid the extrusion jacket when the cable surface appears twist shape, the second is to reduce the cable jacket in the extrusion process too much use of the jacket material. Cable fillers are generally: PP rope, hemp rope, or recycled rubber processing and other generally cheaper materials. Can be used as a cable filling material, must have the insulation cable will not cause adverse effects, the material itself does not have hygroscopicity, not easy to shrink, no corrosion and so on.
Splitter is the fiber optic patch panel sub-line with the optical fiber is the transmission path as long as a fiber on the line

The role of filler: to ensure that the ball round, to avoid extrusion jacket when the cable surface appears twist shape. 2: to reduce the cable jacket in the extrusion process of excessive use of sheath material. Cable fillers are generally: PP rope, hemp rope, or recycled rubber processing and other generally cheaper materials. Can be used as a cable filling material, must have the insulation cable will not cause adverse effects, the material itself does not have hygroscopicity, not easy to shrink, no corrosion and so on.
