10kV Overhead Line Metal Structures with Non-Insulated Conductors

Main Component Types

Grounding Conductors:

Function: Grounding conductors are used to protect the electrical system from surges and electrical leaks. They are connected to the grounding point of the electrical system and direct current into the ground in case of overload or other faults.
Materials: Usually made of galvanized steel or copper, which are corrosion-resistant and ensure long-term reliability even in extreme weather conditions.
Safety Advantages: Grounding conductors protect against electrical leakage, reducing the risk of short circuits, equipment failure, and electrical hazards.
Binding Wire Frames:

Function: Binding frames are used to attach wires to poles and other structural elements, ensuring that wires are securely fastened and stable even in strong winds or other external influences.
Design: Frames have special loops or holders that easily accommodate wires of various diameters, allowing for quick and secure binding without damaging wire insulation.
Durability: Made from galvanized steel or other corrosion-resistant metals, providing long-lasting performance in outdoor conditions.
Crossarms:

Function: Crossarms serve as horizontal holding structures for separating and securing wires on poles, keeping wires at a specific distance from each other to prevent short circuits and wire swaying.
Materials: Made from sturdy galvanized steel that is resistant to corrosion and mechanical impact; galvanization prolongs service life and reduces maintenance costs.
Design Features: Crossarms may include additional insulator holders for reliable wire attachment, ensuring long-term system stability.
Tops:

Function: Tops are mounted on the top of poles for fastening and insulating wires, helping to maintain distance from the pole for stability and safety.
Construction: Made from galvanized steel or aluminum alloys, providing durability and weather resistance, often with special fastening loops or holders for easy and secure wire connection.
Safety Benefits: Tops protect wires from mechanical damage and ensure stability in wind and vibration conditions.
Insulator Holders:

Function: Used for attaching insulators to structural elements like poles or crossarms, isolating wires from the structure to ensure the electrical system’s insulation.
Materials: Generally made from corrosion-resistant steel, capable of withstanding mechanical loads and extreme weather.
Design Features: Holders are designed for easy insulator installation and allow quick replacement or maintenance when needed.
Surge Arrester Holders:

Function: Designed for mounting surge arresters on poles or other structures, which protect the electrical system from lightning and other sudden surges by redirecting excess energy to the ground.
Construction: Made from durable, weather-resistant materials, often using galvanized steel for corrosion protection.
Safety Benefits: Holders enable safe and reliable attachment of surge arresters, ensuring they adequately protect the electrical system from lightning and other surges.
Technical Features

High Resistance Class: All components are adapted for outdoor conditions, offering corrosion resistance, typically achieved through galvanization. This helps maintain structural quality even in extreme weather.
Robust Construction: Made from strong materials capable of withstanding electrical line loads, wind, and other mechanical forces.
Electrical Leakage Protection: Thanks to grounding conductors and insulator holders, these structures minimize electrical leakage risk, enhancing system reliability and safety.
Applications of Use

10 kV overhead line metal structures are used in various sectors:

Energy Sector: Widely applied in power distribution networks, supplying electricity between power stations, substations, and industrial facilities.
Industrial Facilities: Essential for industrial enterprises where reliable and continuous power supply is required, often used in plant electrical networks.
Commercial and Residential Areas: 10 kV overhead lines often serve larger residential neighborhoods and commercial zones where reliable power supply is essential via overhead lines.
Key Advantages

Reliability and Durability: Galvanized steel structures withstand harsh weather conditions, ensuring long service life even in intensive use.
Ease of Maintenance and Installation: Overhead line metal structures are easy to install and maintain, making power network maintenance work faster and more efficient.
Protection from Short Circuits and Surges: Structures such as insulator holders and surge arrester holders ensure the power network is protected from electrical disturbances, avoiding frequent failures.
Stability and Safety: Structures are designed to keep wires stable under all weather conditions, ensuring safe electricity transmission.
10 kV overhead line metal structures with uninsulated wires—grounding conductors, frames, crossarms, tops, insulator holders, and surge arrester holders—are essential elements of electrical transmission and distribution networks. These structures ensure system stability, safety, and longevity, making them crucial for power supply infrastructure in industrial, commercial, and residential settings.
