Suspension Clamp, Service Clamp, Anchoring Clamp, Tension Clamp & High Tension Clamp are some of the crucial components of the AB Cable System. This blog helps you understand the material used for manufacturing, technical features and advantages of various clamps.

Aerial Bundled Cable (ABC) is a new concept for power distribution. It delivers improved safety and reliability, lower power losses, voltage stability, and ultimate system economy by lowering installation, maintenance, and operation costs, compared to the traditional bare conductor OH distribution system.

Axis Suspension Clamps for Insulated Neutral Messenger Systems consist of a body, a movable link, and an adjustable lock. This item is used in conjunction with a pig-tail hook or bracket to suspend and grasp the insulated neutral messenger of an LV-ABC system without destroying it and using an adjustable lock that accepts a variety of cable sizes.

AB Cable Accessories – Different Clamps Explained

Suspension Clamp (Insulated Management System):

Suspension clamp is also known as suspension fitting or clamp suspension. It is an important part of AB Cable Accessories made to suspend the cables or conductors to the pole/ tower. The clamp works with a variety of cables and conductors. The ABC cables are suspended from the suspension clamp at various angles, providing sufficient support and protection.

The material used for manufacturing Suspension Clamp:

• Body:  UV and weather-resistant, high-strength engineering plastic.
• Movable Link: UV and weather-resistant, high-strength engineering plastic.
• Lock: UV-resistant, high-strength engineering plastic.

Technical Features and Advantages of Suspension Clamp:

• NFC 33-040 and other international standards are met or exceeded.
• Long life, safety, cheap maintenance, and lower lifetime cost are all advantages of this product. Engineering plastics give increased insulation, strength, and work on live lines.
• Installation is simple and requires no tools. The design allows for easy turning in congested situations by facilitating longitudinal and transverse movements.

Bracket Feature:

• It has aluminium alloy with high strength and corrosion resistance.
• M14 or M16 bolts or 20×0.7mm SS straps are used for mounting.
• The suspension clamp is kept from turning over thanks to an incorporated metal stopper.

Application of Suspension Clamp:

• Suspension clamps keep the conductor safe immediately at the point of installation.
• It ensures a safe and viable mechanical connection, accomplished by proper longitudinal grip control.

It means that only defined slip loads can release the conductor from the clamp, limiting physical harm. The conductor’s mobility is controlled by suspension clamps, which give protection against the vibrations that severe winds can cause.

Suspension Clamp (Self Support with 2 or 4 Core System):

Suspension Clamp for Self-Supporting Systems suspends and holds the insulated bundle of the LV-ABC system using a bolt and wingnut assembly without the requirement of any additional tools. The product is compatible with a variety of hook bolts.

The material used for manufacturing of Suspension Clamp:

• Body:  Hot-dip galvanized steel
• Insert:  UV and weather-resistant elastomer
• Bolts:  Galvanized steel

Technical Features and Advantages of Suspension Clamps:

• BSEN 50483: Sustains the load of accommodated cable size.

• It accepts a variety of wire sizes and has no replaceable parts, making inventory management easy. It can create straight lines or up to 30° deviation angles, allowing for easy turning in tight places.
• The yoke plate and two suspension clamps may achieve deviation angles of up to 60°, allowing easy turning in congested places. Long life, safety, cheap maintenance, and lower lifetime cost are advantages of this product.

Suspension Clamp (Uninsulated Messenger System):

Uninsulated Neutral Messenger System Suspension Clamp (ACU) for Uninsulated Cables. It suspends and holds the uninsulated neutral messenger. This product is offered in a bolted and adjustable lock type and is customizable.

The material used for manufacturing the Suspension Clamp (SCB1):

• Body: High-strength Aluminum alloy
• Bolts:  Galvanized steel
• Insulation cover:  UV and weather-resistant engineering plastic

Technical Features and Advantages of Suspension Clamps (SCB1):

• The product is designed to support a variety of messenger cable sizes and can withstand the load of the cable size (BSEN 50483, REC and customer-specific requirements).

The material used for manufacturing Suspension Clamps (SCB1-HT):

• Body: High strength Aluminum alloy
• U Bolts and nuts: Galvanized steel

Technical Features and Advantages of Suspension Clamps (SCB1-HT):

• Aids in corrosion protection. The product is designed to support a variety of messenger cable sizes and can withstand the load of the cable size (BSEN 50483 and customer-specific requirements).

Service Clamps:

Service Clamps for Insulated Neutral Messenger System (SAM) is used in conjunction with a bracket or other supporting hardware to strain the insulated service conductor of an LV-ABC system without causing damage to the cable’s insulation. It connects service lines to homes or for street lighting. It is one of the widely used AB Cable accessories.

• Body and Wedges:  UV resistant, high strength engineering plastic.
• Bail:  Stainless Steel.

Technical Features and Advantages of Service Clamps:

• Exceeds NFC33-042 and other international standards.
• Can withstand harsh environments, resulting in an extended life, safety, low maintenance, and lower lifetime costs.
• Has engineering plastics that provide insulation, strength, and the ability to work on live lines without additional tools.
• Two clamps with a bracket for large-angle assembly allows easy turnings. Captive Design Clamp with a bracket for straining saves time and money during installation.

Bracket Feature:

• Heat-resistant with M14 or M16 bolts or 20×0.7mm SS Straps for mounting.
• It is possible to mount up to 6 Service Clamps.

Anchoring Clamps

Anchoring two or four core insulated bundled wires with equal cross-sectional areas is done with  Anchoring Clamps for Self-Supporting System (ACS). The clamp is bolted together and prevents damage to the cable insulation.

The material used for manufacturing Anchoring Clamps:

• Clamping Plates:  Galvanized steel
• Wedges:  UV and weather-resistant, high-strength engineering-plastic
• Bolts:  Galvanized steel

Technical Features and Advantages of Anchoring Clamps:

• Can easily sustain the load of the cable size accommodated.
• It accepts a variety of wire sizes and has no replaceable parts, making inventory management easy.
• The wires are inserted easily due to the spring mounting.
• Withstands harsh circumstances, resulting in an extended life, safety, less maintenance, and a lower total cost of ownership

Tension Clamps (REC Design):

The uninsulated neutral messenger is steadily held in place by  Tension Clamps for Uninsulated Neutral Messenger System. This product is available in a bolted and wedge style to be country, area, and customer-specific.
