Silicone rubber insulated power cable blistering, stomatal reasons What are the improvements?
Silicone rubber insulated power cable blistering, stomata is caused by the process problems, silicone rubber insulated cable in the injection should be used when the vacuum casting, raw materials to fully degassed, otherwise there will be blistering and stomata, some small factories because there is no vacuum Injection equipment, coupled with poor degassing process will produce this poor product, to solve this problem is the first workshop to maintain constant temperature and humidity, the purchase of excellent performance of the vacuum injection equipment and vacuum mixing equipment, strict control of process parameters. Silicone rubber power cable for AC rated voltage 0.6 / 1KV and below fixed power transmission line or mobile electrical connection cable, the product has heat radiation, cold, acid and corrosive gases, waterproof and other characteristics, the cable structure is soft, Radiation, high temperature (alpine) environment, electrical performance and stability, anti-aging performance, long life, widely used in metallurgy, power, petrochemical, electronics, automobile manufacturing and other industries
Meaning the cross-sectional area of the wire, the unit is square mm; for example: 4 square copper wire, the cross-sectional area of the wire is 4 square millimeters, copper wire;
Surface brush fireproof paint is the fire-resistant bridge by fire time sub-level two three times as if 30 minutes 45 minutes and 60 minutes fire bridge should be lined with inorganic fire board, but this is very high in the general very little useful
In this only said home improvement commonly used, the pipe is basically direct, elbow, tee, the price is 5 points / only.
