The main function of the stainless steel cable gland is to keep the cable circuit unblocked and ensure the airtightness between the cable connections. At the same time, it guarantees the insulation level at the cable interface to ensure that the cable can run safely. Otherwise, it may cause oil leakage, causing the oil-impregnated paper to dry out, and unable to block the moisture intruding into the cable, causing the insulation performance of the cable interface to decrease. So, how to use a stainless steel cable gland correctly? Here is a brief introduction for everyone.
1. When using stainless steel cable glands, the entire shape and size need to be accurate. The potential distribution on the cone surface should be equal. When making the cross-linked cable reaction cone, use cutting tools as much as possible. You can also use a small fire for a little heating, and then cut. After approximately forming, use about 2 mm thick glass for scraping, and finally use sandpaper to carefully polish from coarse to fine until the cross-linked cable reaction cone becomes smooth.
2. The main function of the metal shield of the stainless steel cable connector in the cable and the connector is to conduct the short-circuit current of the cable fault, and at the same time to shield the electromagnetic interference of the electromagnetic field on the adjacent communication equipment. In the operating state, the metal shield is at zero potential if it is in a good grounding state. If the cable fails, the metal shield of the stainless steel cable connector can conduct short-circuit current in a very short time.
3. The sealing and protection of stainless steel cable glands is a guarantee to ensure the safe operation of the joints. It is necessary to prevent moisture from penetrating into the cable connector. On the other hand, at the location of the connector, a connector protection slot or a cement protection box should be built.
In short, when using stainless steel cable glands, you must follow the formal steps and correct protection procedures, so as to ensure the safe and reliable operation of the cable.
