What Is An Anchoring Clamp？

With the development of the times, electricity and communication have become indispensable parts of our lives. Towering utility poles have sprung up everywhere. How to protect these overhead lines has become a problem, and anchoring clamps have emerged to address this problem. Please follow this guide to learn what an anchoring clamp is and what it does.

As the name suggests, anchoring clamps serve an anchoring function and can be used in your power and communication lines.

The purpose of anchoring clamps is to suspend your cables while sharing the tension of the line and protecting the cable insulation from damage.

Which application areas are anchoring clamps used?

1.Low/medium/high voltage overhead power lines:

The insulated cable termination of the 0.4 kV power distribution network suspends the cable on poles, walls, and supports to share the tension.

For 6–35 kV medium voltage lines, anchor clamps are used to secure the insulated conductors on the poles.

The anchoring clamp, forged from high-strength aluminum alloy, can withstand the tension of 35 kV and 110 kV transmission lines and is used in conjunction with insulators.

2.Communication and FTTx Optical Cable:

It can be used for terminal poles and tension sections of short span self supporting optical cables (ADSS), using wedge shaped tension anchors to secure the cable to the pole, preventing wind swaying and creep.

For FTTH drop sections, small anchors are used to secure the introduced optical cable at pole locations and building transitions, enabling stable transmission through the exterior wall of the pole without loosening.

3.Photovoltaic power station and wind farm power collection lines:

It can be used for 1–35 kV overhead insulated lines between fixed distributed inverters and transformer substations. It is often treated with aluminum alloy anchoring clamps at the terminal poles to withstand the tension of large spans on a single slope.

4.Temporary power and lighting lines:

For lighting cables at construction sites, markets, and temporary squares, when the span is less than 100 m, lightweight anchoring clamps can be used to quickly tighten and fix the cables.

What are the advantages of using anchoring clamps?

1. The retaining ring is detachable and made of hot-dip galvanized steel wire, making it easy to install.
2. Preventing wind load vibration.
3. The cable insulation layer will not be stripped during installation, making it safe and convenient.
4. Suitable for various voltage lines and various span lengths.
5. This clamp is made of high-strength plastic/aluminum alloy, which is resistant to high temperatures, sun exposure and ultraviolet radiation, and can withstand frost.

What factors should be considered when selecting anchor clamps?

1. Cable diameter
2. Cable type
3. span between overhead line systems
4. Cable tension requirements
5. Environmental conditions (temperature, ultraviolet radiation, humidity)

How do anchoring clamps protect cables?

1. To prevent cable transmission system failures caused by wind, cable weight, or freezing.
2. Reduce the risk of cable damage.
3. Extend the service life of overhead communication lines.
4. Provides a robust connection without damaging the cable insulation layer.
5. Resisting the tensile and rotational forces borne by the line.

What materials are the various components of the anchoring clamp made of?

Body: High-strength cast aluminum alloy or durable plastic

Wedge shaped parts: Made of UV-resistant and weather-resistant high-strength plastic or nylon.

Fixing clips: Made of aluminum alloy, highly corrosion resistant.

Fixed ring: hot-dip galvanized steel wire.

How to maintain anchor clamps?

1. Regularly check cables for damage or looseness, and replace or tighten them promptly.
2. Clean regularly to remove dirt and corrosive substances.
3. Use a suitable lubricant to enhance the durability of the anchor clamp.
4. Replace or repair damaged fixtures promptly.
5. Store in a dry, sheltered place to avoid exposure to humid air.

What other overhead line accessories might you need?

1. Insulator
2. Drop Wire Clamp
3. Insulation Piercing Connector
4. Stainless Steel Banding
5. Electrical Cross Arm
6. Pole Bracket
7. Guy Grip
