utp cable joints, not previously explicitly requested or required method of grounding the metal layer. Years of operation and practice, no standardized method for power and ground operation, maintenance and repair have different degrees of impact, it is necessary for the grounding cable connector metal layer method unified regulations. 1. Terminal head armored and copper shield utp cable terminals should be separately grounded with stranded conductors with insulation alone. Section of copper shield grounding wire shall not be less than 25mm. ; Armored ground wire cross-section of not less than 10mm. .
2. Middle connector
Copper ground wire in the middle connector shield and armor shall be connected together, the middle connector on both sides of armored ground must be connected with the other lines, but also must be insulated with copper shield. utp cable accessories such as when the original structure is no inner liner, should be added in the outer lining layer copper shield, but also with cable glands lining the body must be a good lap, which must maintain the integrity and continuity of the cable . Armored ground external connections must have outer sheath, and has the same outer sheath and the cable insulation and sealing properties, namely the need to ensure the integrity of the cable sheath and continuity.
