Technical Specifications
Engineering data
Bowl head products, a type of essential power hardware widely used in power transmission and distribution systems, are mainly applied in power systems, including high-voltage transmission lines, substations, and power distribution networks. As the core components of connecting hardware in power engineering, their design and functions must strictly comply with the requirements of high voltage resistance, strong environmental adaptability, and high mechanical strength, ensuring stable, safe, and reliable operation in various complex working conditions such as high temperature, low temperature, humidity, and corrosive environments. These products play an irreplaceable role in maintaining the integrity of the power grid and ensuring the smooth transmission of electrical energy.
As a key accessory in power transmission lines, the bowl head hanging plate is specially designed to connect suspension wire clamps and insulator strings, which is one of the most critical connecting parts in overhead power lines. It achieves firm and reliable connection between conductors and insulators through scientific and reasonable structures such as internal and external twisted wires, high-quality rubber clamps, and precision-machined connecting ports. This connection method not only ensures the tightness and stability of the connection but also effectively absorbs the vibration generated during the operation of the power line, reducing the wear of components and effectively ensuring the integrity, safety, and long-term stable operation of the power line.
Mechanical Connection: With excellent load-bearing capacity, the product can stably bear the tension of conductors during power transmission and the weight of insulator strings, effectively resisting the impact of external factors such as wind load and ice load. It ensures the overall stability of the power line, avoids line sag, displacement, or even disconnection caused by insufficient load-bearing capacity, and further guarantees the safe and stable operation of the entire power transmission system.
Insulation Guarantee: The bowl head products are closely matched with insulator strings to form a complete electrical insulation system, providing excellent electrical insulation performance. This insulation protection can effectively isolate the conductor from the ground and other components, prevent the risk of electric leakage, short circuit, and other electrical faults, avoid potential safety hazards such as equipment damage and personal injury, and ensure the safe and stable operation of the entire power system.
Structural Optimization: In terms of structural design, the product adopts advanced processes such as hot-dip galvanizing, which forms a dense and firm anti-corrosion layer on the surface of the product. This anti-corrosion layer can effectively resist the erosion of corrosive substances such as moisture, salt spray, and acid rain in the environment, significantly enhancing the product’s corrosion resistance and weather resistance. At the same time, this optimization also effectively extends the service life of the product, reduces the frequency of product replacement and maintenance, and further reduces the operation and maintenance costs of power projects.
Voltage Level: The product has a wide range of voltage adaptation, covering 10kV to 220kV transmission lines and substations, which can fully meet the use needs of different voltage grade power projects, including urban power distribution, rural power supply, industrial power transmission, and long-distance high-voltage power transmission. Its stable performance under different voltage levels makes it a versatile and practical connecting component in the power industry.
Material: The main materials of the bowl head products are high-quality ductile iron and malleable cast iron. These two materials have excellent mechanical strength, toughness, and wear resistance, which can fully meet the harsh working requirements of power connecting hardware in complex environments. After strict material selection and precision processing, the products have good impact resistance and load-bearing capacity, ensuring that they can operate stably for a long time in various harsh working conditions without deformation or damage.
Non-standard Customization: In order to meet the diverse needs of different power projects, we provide professional non-standard customization services. According to the specific line parameters (such as conductor cross-section, tension requirements), special environmental conditions (such as high-altitude, coastal, cold areas), and customer-specific needs, our professional R&D and production team will carry out customized design and production, ensuring that the customized products can perfectly match the actual needs of different projects and provide the most suitable connecting solutions for customers.

Technical FAQ
Application limits
- Can it be used for steam above 150 C?
- No. Do not use for steam above 150 C unless a written project-specific approval, rated gasket, and compatible body material are confirmed.
- Can it replace any grooved fitting without checking pipe OD?
- No. Pipe OD, groove standard, working pressure, gasket material, and certification scope must be matched.
- Is it suitable for potable water by default?
- No. Potable water use requires confirmation of coating, gasket compound, local sanitary approval, and project compliance.
- Can it be used in corrosive chemical service?
- Not by default. Chemical compatibility must be verified against the medium, concentration, temperature, and coating system.
