When sets of quotas when the power cable and control cable
C-PVC cable jacket and PVC-U drainage pipe difference: . material: C-PVC is CPE and PVC mixed with the material, CPE is chlorinated polyethylene, can be used as high-performance, high-quality special rubber. PVC-U, also known as hard PVC, which is vinyl chloride monomer by polymerization reaction made of amorphous thermoplastic resin plus certain additives such as stabilizers, lubricants, fillers and other components. In addition to the addition of additives with other resins used in the blend of modified approach, it has a significant practical value. Melt viscosity is high, poor mobility, even if the increase in injection pressure and melt temperature, mobility changes are not large. . appearance: C-PVC cable jacket are generally black, and PVC-U drain are generally white. . use: C-PVC cable jacket is generally used in telecommunications, power engineering, transportation, urban construction and other fields. PVC-U drainage pipe mainly bear the rain, sewage, farmland irrigation and drainage tasks. . C-PVC cable sheathing high temperature; PVC-U drainage pipe is smooth, the resistance is relatively small, resistant to erosion.
As long as there is no contact bad that the interface of the loss is nothing
If your wire is in the thread when the insulation is broken even a little bit, or the existence of quality problems with the wire encountered when the water or damp will cause a short circuit. (Upstairs tenants do not admit that the water is not admitted, but also invited his decoration master to see, they say no matter what the situation, even if the water leakage will certainly not lead to short circuit.) Is his decoration master? Funny right? First of all, you have to find a professional electrician master to let him use [shake table] or megger to detect whether the line there is a short circuit phenomenon, if there is upstairs in the upstairs and then check, and then consult. Second, you find out the place to find a good leak to ensure that the stability of ten to be able to find people theory.
