JBLY, JBTY, JBTLY series special-shaped parallel groove clamps are suitable for non-stressed connection and branching of wires in overhead power lines (small and medium-section aluminum stranded wires or steel-cored aluminum stranded wires and steel stranded wires of overhead lightning protection wires that do not bear tension It is also used for jumper connection of non-straight pole towers.), it is used in conjunction with an insulating cover to protect and insulate. ●Structural features: 1. Select anti-oxidation aluminum alloy material 2. Tooth structure, small contact resistance, reliable connection 3. The parts are connected together, and the parts will not be dropped during installation 4. The arc is held tightly in a large area, and the wire is not easy to creep ●Insulation cover performance characteristics: 1. Power frequency withstand voltage: ≥18kV hold voltage for 1 minute without breakdown 2. Insulation resistance: >1.0×1014Ω 3. Ambient temperature: -30℃~90℃ 4. Weather resistance: good performance after 1008 hours of artificial weather aging test
