Product Description
The company is the world’s best pg clamps in transmission line supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.
Suspension clamps are used to hang conductors or ground wires to insulators or link fittings to tower arms and substation structures.
A suspension clamp is designed to give the conductors both physical and mechanical support. This is important especially when you have installed the conductors for the power transmission line and even telephone lines.
Suspension clamps enhance the stability of the conductor by limiting their movements especially against a strong wind, storm, and other vagaries of nature.
Made of aluminum alloy or malleable cast iron, suspension clamps are characterized by their strength, durability, and reliability. The aluminum alloy suspension clamp is lightweight and corrosion-resistant, making it easy to handle and suitable for various environments. The malleable cast iron suspension clamp offers high tensile strength, impact resistance, dimensional stability, and heat resistance, making it ideal for heavy-duty applications and elevated temperatures.
Suspension clamps feature a clever ergonomic design that ensures that the weight of the conductor is evenly distributed on the clamp’s body. This design also provides perfect angles of connection for the conductor. In some cases, counterweights are added to prevent the conductor’s uplift.
Other fittings such as nuts and bolts are used along with the suspension clamps to enhance the connection with the conductors.
You may also request a custom design of a suspension clamp to suit your application area. This is vital since some suspension clamps are designed for single cables while others are for bundle conductors.
Custom size and requirements are available upon request.

Introduction to Suspension Clamps
Suspension clamps are hardware devices designed to suspend and secure overhead cables, preventing them from sagging or being damaged due to environmental conditions or mechanical stress. These clamps play a critical role in maintaining the integrity and reliability of electrical systems, ensuring optimal performance and safety.
Importance of Suspension Clamps in Electrical Installations
Suspension clamps are essential in electrical installations for several reasons. Firstly, they provide mechanical support to overhead cables, preventing excessive sagging and maintaining the desired clearance from the ground or other objects. This helps to prevent damage to the cables and ensures consistent performance.
Additionally, suspension clamps help to distribute the weight of the cables evenly, minimizing stress on individual conductors and supporting structures. They also aid in reducing vibrations and oscillations caused by wind or other external factors, which can lead to wear and tear or electrical disturbances.
Factors to Consider When Buying Suspension Clamps
When purchasing suspension clamps, it is essential to consider several factors to ensure the right fit for your specific application. Here are some key factors to keep in mind:
Durability and Strength
Suspension clamps should be made from high-quality materials that can withstand environmental conditions, such as temperature variations, humidity, and exposure to UV radiation. The clamps should also have sufficient strength to support the weight and tension of the cables they are designed for.
Material Composition
Suspension clamps can be made from various materials, including stainless steel, aluminum alloy, and composite materials. Each material has its advantages and considerations in terms of strength, corrosion resistance, conductivity, and cost. The choice of material depends on the specific requirements of the installation.
Load Capacity
It is crucial to determine the maximum load capacity of the suspension clamp, which should match the anticipated load of the cables it will support. Exceeding the load capacity can compromise the structural integrity and safety of the installation.
Installation Method
Different suspension clamps have varying installation methods, such as bolted, wedge, or preformed clamps. The installation method should be compatible with the type of cable and the installation environment. It is essential to follow the manufacturer's guidelines for proper installation.
Compatibility with Cable Type
Suspension clamps are designed for specific cable types, such as bare conductors, insulated cables, or optical fiber cables. It is crucial to ensure that the clamp is compatible with the cable type to ensure proper gripping, electrical continuity, and insulation integrity.
Different Types of Suspension Clamps
Suspension clamps are available in various designs to accommodate different installation requirements. Here are some commonly used types of suspension clamps:
Parallel Groove Clamps
Parallel groove clamps are widely used for bare conductors and are designed with grooves that securely grip the conductors. They provide excellent mechanical strength and electrical conductivity.
U-Bolt Clamps
U-bolt clamps feature a U-shaped bolt that holds the cable in place against a saddle. They are commonly used for securing aerial bundled cables and provide a secure and reliable connection.
Wedge Clamps
Wedge clamps utilize a wedge-shaped piece that tightens against the cable, holding it firmly in place. They are often used for self-supporting cables and offer quick and easy installation.
Bolted Suspension Clamps
Bolted suspension clamps feature bolts that securely fasten the clamp to the supporting structure. They provide high load capacity and are suitable for heavy-duty applications.
Preformed Suspension Clamps
Preformed suspension clamps are designed with a preformed grip to match the shape of the cable, providing optimal support and reducing stress concentrations. They are commonly used for optical fiber cables.

Understanding Suspension Clamp Specifications
To make an informed buying decision, it is essential to understand the specifications associated with suspension clamps. Here are some key specifications to consider:
Maximum Load Capacity
The maximum load capacity indicates the maximum weight that the suspension clamp can support without compromising its integrity or safety. It is important to select a clamp that matches or exceeds the anticipated load requirements.
Conductor Range
The conductor range specifies the diameter or size of the conductors that the suspension clamp can accommodate. It is crucial to choose a clamp that fits the specific conductor size to ensure proper gripping and electrical continuity.
Diameter Range
The diameter range refers to the allowable range of cable diameters that the suspension clamp can accommodate. It is essential to select a clamp that matches the diameter of the cables to ensure a secure fit.
Insulation Type
For suspension clamps used with insulated cables, it is important to consider the compatibility with the insulation material and the specific requirements for insulation integrity and electrical safety.
Temperature Rating
Some suspension clamps have temperature ratings that indicate the range of temperatures they can withstand without compromising their mechanical properties or electrical performance. This is especially important for installations in extreme temperature environments.
Proper Installation Techniques for Suspension Clamps
Proper installation techniques are crucial to ensure the effectiveness and longevity of suspension clamps. Here are some important steps to follow during the installation process:
Pre-Installation Checks
Before installing suspension clamps, it is important to conduct pre-installation checks, such as inspecting the clamps for any visible defects, verifying the compatibility with the cable type, and ensuring all necessary accessories and hardware are available.
Correct Alignment and Positioning
The suspension clamps should be aligned correctly and positioned at the desired locations along the cable route. Proper alignment and positioning help to distribute the weight evenly and prevent excessive stress on individual clamps.
Adequate Torque and Tightening
During the installation process, it is essential to apply the correct torque and tightening to ensure a secure and reliable connection. Under-tightening can result in loose clamps, while over-tightening can damage the clamps or cables.
