Single-core cable line grounding line commonly used grounding 1. shield one end directly grounded, the other end through the protective layer to protect the ground: When the line length of 500 --- 700m and below, the shield can be used directly to one end of the ground (cable terminal Position ground), the other end through the protective cover to ground. 2. shield the midpoint of the ground: When the line length of 1000 ---- 1400m, the use of midpoint grounding. in the middle of the line position, the shield directly grounded, the cable ends of the shield through the protective cover to ground. The middle ground is usually required to install a straight connector. Install an insulated connector at the midpoint of the line. The insulated connector disconnects the cable shield, and the shield is grounded through the protective cover, and the two cables are shielded and grounded directly. 3. Shielded cross-connect cable lines are very long (1000 --- 1400m above), you can use shield cross-connect. This method is divided into three equal parts of the length of the three or three times the number of segments, each section between the installation of insulation joints, insulation joints between the three-phase shield with a coaxial cable, cross-linked box for transposition, cross The interconnection box is provided with a set of protective protector, and the two sets of insulated connectors are arranged on the line.
