How to deal with problems that occur when using European cable connectors?
Internal semiconductor shielding treatment
If the cable body has an inner shielding layer, the inner shielding layer of the joint that presses the receiving conductor part must be restored when making the joint. A part of the inner semiconductor shielding of the cable must be set aside so that the inner shielding of the connector on the connection can be connected to each other to ensure the continuity of the inner semiconductor, so that the field strength at the joint receiving point is evenly distributed.

Treatment of external semiconductor shielding
The outer semiconductor shield is a semiconductive material that acts as a uniform electric field on the outside of the insulation of cables and cable joints. Like the inner semiconductor shield, it plays a very important role in cables and joints. The external semiconductor port must be neat and uniform and must have a smooth transition with the insulation, and a semiconductor tape must be added to the cable joint to connect with the external semiconductor shield of the cable body.
Treatment of cable reaction force cone
During construction, the reaction cone with accurate shape and dimensions will have a flat potential distribution on the entire cone surface. When making cross-linked cable reaction cones, special cutting tools are generally used. You can also heat it slightly with a low flame and cut it with a sharp knife. After it is basically formed, use 2mm thick glass to scrape it, and finally use sandpaper to polish it from coarse to fine until it is smooth.

Metal shielding and grounding treatment
The function of metal shielding in cables and joints is mainly to conduct short-circuit current in cable faults and to shield electromagnetic fields from electromagnetic interference on communication equipment. During operation, metal shielding is at zero potential in a well-grounded state. When a cable fails, it has the ability to conduct short-circuit current in a very short period of time. The ground wire should be reliably welded, the metal shield and armor tape on the cable body at both ends should be reliably welded, and the grounding of the terminal head should be reliably welded.
