ADSS Cable Accessories Guide – Anchor Clamp

Introduction:

With the rapid development of the global telecommunications industry, the application of ADSS cables and ADSS accessories is increasing. So we have carefully compiled this guide to help you improve your knowledge of ADSS cable accessories – anchor clamp.

What are ADSS Anchor Clamps?

ADSS anchor clamps also called ADSS tension clamp, wedge type tension clamp and dead end clamp. They are specialized overhead hardware for supporting ADSS cables. Their main function is to anchor ADSS optical cables to utility poles and towers, enabling the cables to change direction, preventing slippage and damage.

The difference between ADSS suspension clamp and anchor clamp

ADSS suspension clamps provide intermediate support for the straight cable span; they primarily bear the vertical load generated by the weight of the cables themselves. Anchor clamps need to be installed at the end of the utility pole or tower to bear the lateral tension of the entire power/communication systems. Understanding their key differences is crucial for selecting the right accessory.

What are the functions of ADSS anchor clamps?

In cable systems, ADSS anchor clamps have the following core functions:

Balancing cable tension: ADSS anchoring clamps distribute stress (cable weight, wind load, and lateral tension from cable sag) by clamping the cable.

Fixed position and change direction: It can fix cables at the end of utility poles or towers to prevent them from slipping, shifting, or changing direction, thus facilitating fiber optic cable installation.

Protective effect: High-quality ADSS anchoring clips share stress while protecting the cable insulation from damage and preventing stray currents from affecting line transmission.

What are the application scenarios?

1. Fiber to the home distribution terminal
2. Long-span overhead cable anchoring
3. Change the direction of power lines on poles or towers
4. Unique coastal (salt spray) environment, high-altitude (low temperature, low pressure) environment, high temperature, and sun exposure environment, etc.

What is the working principle of the ADSS anchor clamp?

Its working principle is based on the mechanical principle of wedge self-locking, and its design principle is to convert external stress into its own tension force. Through the friction of the cable on the wedge block, the wedge block is pulled downward and pressed deeper into the main body shell. The greater th hae pulling force, the stronger the clamping force.

What are the classifications of ADSS tension clamps?

The tension clamp can be classified by their span:

Short span anchoring clamp

Commonly used in the last mile of fiber-to-the-home (FTTH) installations, compact anchor clamps with a delicate design and low clamping force can be used. PA2/25 to PA600 are all suitable for short-span anchoring.

Mid-span anchoring clamp

For overhead line anchoring at lengths of 100m, these anchoring clamps can withstand higher stress and loads. They are typically reinforced with aluminum alloy housings, are larger in size, andve greater clamping force. PA1500 and PA2000 are perfect fits.

Long span anchoring clamp

Anchoring for spans exceeding 200m requires custom-made anchoring clamps, which are commonly used in scenarios such as river crossings and valley crossings.

You can also choose the appropriate ADSS anchor based on the cable diameter:
