JBK,JBT,JBKG(JKY,JBL) span parallel trench line clampDetailed product description：

JBK, JBT, JBKG (JKY, JBL) span parallel groove line clamps are suitable for non load bearing splicing and branching of overhead power lines, with the characteristics of easy and flexible installation, and a wide range of applicable wires. The JBKG series copper aluminum span clamps use friction welding or brazing processes for users to choose from. The insulation cover is used in conjunction with the wire clamp to provide insulation protection.

Performance characteristics of insulation cover
Power frequency withstand voltage: ≥ 4kV withstand voltage for 1 minute without breakdown or flashover;
Insulation resistance:>1.0 × 1014 Ω Environmental temperature: -300C~900C
Climate resistance: Good performance after 1008 hours of artificial climate aging test
This insulation cover is suitable for overhead power lines of 10kV and below
