Suspension clamps play a crucial role in ensuring the safe and efficient operation of aerial bundled (AB) cables used in electrical distribution and transmission systems. These clamps are vital for maintaining proper tension, preventing excessive cable sag, and mitigating the risk of electrical hazards.
Suspension clamps are typically manufactured using high-strength materials such as forged steel, aluminum alloys, or composite materials. They consist of two main components:
There are various types of suspension clamps designed specifically for AB cables. The most common types include:
Choosing the right suspension clamp for your AB cable application requires careful consideration. Factors to consider include:
The global market for suspension clamps for AB cables is expected to grow significantly in the coming years, driven by increasing investments in electrical infrastructure and the growing adoption of AB cables. The market is also witnessing technological advancements, such as the development of composite clamps with enhanced durability and reduced weight.
