Main Features and Functions

Overhead Line Cable Mounting Frames
Material: Typically made from high-quality steel or aluminum, ensuring high resistance to corrosion and mechanical impact.
Design: Frames are often suitable for both horizontal and vertical installation, depending on the structure and specifications of the lines.
Function: The primary function of the frames is to secure the cable, ensuring it remains firmly in place and maintains stability even under strong winds or other mechanical loads.
Mounting Types: Frames may include various mounting elements such as spring-loaded or adjustable tension mechanisms that ensure secure cable holding.
Cable Covers
Material: Covers are usually made from durable plastic or composite materials that are resistant to UV rays, moisture, and temperature fluctuations.
Design: Covers must be strong enough to protect the cable from atmospheric elements (e.g., rain, snow, wind) and prevent contamination such as dust and small particles from reaching the cable.
Protection: The primary function of the covers is to protect the cables from mechanical damage and external influences, ensuring a longer cable lifespan and reducing the likelihood of malfunctions.
Technical Specifications

Frames and covers must be resistant to high temperatures, UV rays, rain, snow, and wind, often incorporating composite or stainless steel elements.
Moisture Resistance: IP65, IP67 (depending on the product type), providing protection against dust and water.
Temperature Range: Typically from -40°C to +70°C, to withstand various weather conditions in both winter and summer.
Sizes: Frames and covers come in different sizes to accommodate various cable types and diameters, allowing them to be adapted to both small and large cables.
Mounting Methods: Cable mounting can be done via tension mechanisms, allowing the tightening strength to be adjusted according to the cable load and weather conditions.
Applications

High and Medium Voltage Overhead Lines: Frames and covers are widely used in electrical transmission lines where cables are suspended on poles, transmitting large amounts of electricity over long distances.
Industrial Zones: These accessories are also used in industrial and manufacturing facilities where overhead lines provide electricity to various devices or systems.
Residential and Commercial Buildings: Frames and covers are also used in commercial and residential buildings where safe power supply lines need to be created to prevent electrical losses and damage due to bad weather conditions.
Advantages

Protection from Mechanical Damage: Covers ensure that cables are protected from external mechanical damage, such as impacts, scratches, or wear.
Protection from Atmospheric Elements: Frames and covers protect cables from moisture, temperature fluctuations, and UV rays, helping to ensure their durability.
Stable Cable Mounting: Frames ensure that cables are firmly secured, reducing the risk of voltage fluctuations and mechanical failures.
Ease of Mounting: Frames and covers are easy to install, enabling quick and efficient cable installation and mounting.
High Durability: Frames and covers often feature high resistance to chemical agents, making them long-lasting and suitable for use in harsh environments.
Disadvantages

Limited Use in Wet and Unprotected Areas: Some frames and covers, especially those with an IP20 rating, are unsuitable for use in damp or open outdoor conditions without additional protection.
Cost: High-quality, durable overhead line frames and covers may be more expensive than basic cable mounting solutions.
Need for Regular Maintenance: Although these accessories ensure reliable cable mounting and protection, they require periodic maintenance to ensure long-term operational quality.
Conclusion
Overhead line cable mounting frames and cable covers are essential components that ensure safe and efficient cable installation in both high and medium voltage overhead lines. They provide additional protection against atmospheric elements and mechanical damage, extending the lifespan of cables. These accessories are crucial in both industrial and residential areas where overhead lines are used to supply electricity, ensuring uninterrupted and safe electrical power delivery.
