Clamps for air line cables | cables | equipment mounting

Technical Data

Material:

Aluminum: Used for its light weight and good electrical properties.
Steel: Used for strong resistance to mechanical loads.
Stainless steel: Often used in places where corrosion resistance is required, such as outdoor conditions.
Composite materials: Some clamps are made from composite materials, offering good resistance to environmental factors and durability.
Voltage and Load:

The clamps are designed for use in both low voltage (0.6 kV) and high voltage (up to 500 kV and beyond) overhead lines, depending on their design and purpose.
The clamp must withstand loads corresponding to the weight of wires and cables, wind loads, and temperature changes.
Degree of Protection:

Clamps typically have a high degree of protection (IP20, IP65 and above) to protect wires from moisture, dust, and other environmental factors.
Mounting Type:

Horizontal Clamp: Suitable for wires mounted in a horizontal position.
Vertical Clamps: Used for mounting wires in a vertical position or on poles.
Operating Temperature:

The clamps for overhead lines can operate in various temperature ranges depending on the materials from which they are made, but typically from -40°C to +70°C.
Application:

Overhead Line Wire Attachment: Clamps are used to secure overhead line wires to supports, ensuring their stability and protection from external factors such as wind, snow, and other mechanical stresses.
Wire Protection: Clamps not only secure wires but also protect them from potential damage, especially in areas where the lines pass through difficult or harsh environmental conditions.
Cable Systems Holding: Overhead line cable clamps are used to secure cable systems in both high and low voltage lines to ensure stability and prevent tension on the cables.
Branch and Tap Connections: Clamps are often used for connecting branches or taps to the main line in overhead power lines.
Specialized Use Locations: Suitable for use in both residential and industrial areas where reliable energy transmission and protection are crucial.
Pros:

Reliability and Safety: Clamps provide a secure and stable hold for wires, protecting them from mechanical damage and reducing the risk of failure.
Resistance to Environmental Factors: Due to the high-quality materials used, clamps are resistant to UV rays, moisture, and other harsh environmental conditions.
Versatility: Various types of clamps are available, suitable for different overhead line projects, whether residential, industrial, or high-power networks.
Easy Installation and Adjustment: Most clamps are easy to install and adjust according to line requirements.
Durability: Resistant to corrosion and temperature changes, providing a long service life, especially in outdoor conditions.
Cons:

High Load Costs: In areas requiring higher resistance to mechanical impact, clamps can be heavy and expensive.
Installation Requirements: To ensure proper clamp operation, it is important to follow installation instructions and pay attention to material selection to ensure optimal performance and longevity.
Limited Resistance to Extreme Conditions: Some clamps may not be sufficiently resistant to extremely harsh weather conditions or specific manufacturing environments (e.g., very high temperatures or exposure to particular chemicals).
Clamps for overhead lines are an essential component to ensure the stability and safety of electrical wires and cables in overhead lines. They are resistant to various environmental conditions and can be used in both low and high voltage lines in residential and industrial areas. Properly selected and installed clamps ensure long-term and effective wire holding and protection from various external factors, making them essential for reliable and safe energy transmission.
