1.1A/B series are suitable for connection of non-insulated wires of 25-120mm². Made of highly mechanical and climatic insulating materials. Lock and clamp the dropped neutral with the notched arm connector. Provides important accessory insulation between pole and cable. ES/PS series is suitable for 35-70mm² insulated wire. It is composed of hanging wire clamp and hanger CS aluminum alloy single piece, CS is fixed on the rod with a diameter 12 or 16mm bolt and two kinds of stainless steel bands (20*0.7mm). 1. Simple installation: the cable branch can be made without stripping the insulation skin of the cable, and the connector is completely insulated. The cable clamp can create branches anywhere in the cable without interrupting the main cable. The installation is simple and reliable, and the socket wrench can be used for charging. 2. Use safety: to prevent connector distortion, impact, water resistance, flame retardancy, and electrical corrosion aging. The cable clamp does not need maintenance. 3. Cost reduction: The cable clamp occupies a very small area, which can save tray and civil construction costs. It is applicable to buildings and reduces investment in terminal boxes, junction boxes, cable clamps and cables. The cost of the cable puncture clamp is lower than that of other power supply systems, accounting for only about 40% of the bus connection and only about 60% of the prefabricated branch cable. 4. The insulation performance of the material itself is good, so this cable clamp can directly contact the outer sheath, will not produce eddy current loss, and improve the power transmission capacity to reduce cable damage.
