AB Cable Accessories are essential components of an Aerial Bundled Cable (ABC) system, ensuring safe and reliable power distribution. They provide support, strain relief, secure connections, and termination points for ABC systems without damaging the cable’s insulation.
These accessories include suspension clamps, anchoring clamps, service clamps, insulation piercing connectors, midspan joints, pre-insulated bimetallic lugs, and low voltage distribution boxes.
The clamps and connectors mentioned above undergo load tests, slip tests & endurance tests to ensure that the device can withstand the load conditions of the AB Cable in real-world scenarios without slippage. The midspan joints and pre-insulated bimetallic lugs are put through their mechanical tests after the crimping of the products. The insulation-piercing connectors also have to make their connection without causing damage to the conductor. Thus, the tap and main conductor are put through a tensile strength test after the application of the IPC to ensure that cable strands have not been cut through the application of the product which would weaken the conductor.
Accessories such as clamps and connectors undergo a 6 kV test to ensure that none of their components become electrified during operation, promoting the safety of power line workers or any person who may accidentally touch the product. Insulation Piercing Connectors (IPCs) are tested to a 6 kV underwater test to ensure a waterproof connection without any electrical leakage. Low Voltage Distribution Boxes are tested for surges from 2 kV to 4 kV to ensure no leakage current and intact performance during an electrical surge.
Since the accessories are used in outdoor overhead power distribution systems, they must be able to withstand harsh environmental conditions. Clamps are tested for corrosion and climatic aging to ensure their durability against direct sunlight, rain, and other outdoor elements. Distribution boxes undergo tests for the effects of UV rays on the product, ensuring they can withstand long-term exposure to sunlight.
By conducting comprehensive electrical and environmental testing, Axis ensures that their AB Cable Accessories are safe, reliable, and suitable for outdoor power distribution systems.
