There are various classifications of Power Line Hardware, which are mainly divided into the following categories:
①. Connecting fittings, mainly used for overhead power lines in the construction of electric power fittings and substations constructed by the electric power bureau. The general function is to use connecting fittings to form a string of suspended insulators and hang them on the tower. The function is to use the connecting hardware to connect the suspension clamps for linear towers or the tension clamps for non-linear towers and the insulator strings together, and there are many places where the connecting hardware can be used.

②. Suspension clamp, this type of power fittings is mainly suitable for hanging wire insulator strings on towers and hanging jumpers on insulator strings.

③.Protection fittings, as the name implies, are mainly reflected in the protection of other power fittings, reducing the vibration amplitude of overhead power line wires and lightning conductors, as well as the uniform shielding of lines above 330kv and substation insulator strings. Such products include: Vibration Damper, spacer bars, etc.

④.Tensile fittings are mainly used in overhead power lines and substations to fix conductors and lightning conductors, and then connect with some tensile insulators through matching and connecting fittings, or connect lightning conductors to towers. This type of power fittings can be divided into three categories according to the installation method and structure: bolt type, compression type, and wedge type. In addition, the compression type is divided into two types: explosion pressure and hydraulic pressure.

According to the purpose, the power fitting cross arm can be divided into linear cross arm, corner cross arm and tension cross arm. The cross arm is an angle iron fixed horizontally on the top of the utility pole. There is a porcelain bottle on it, which is used to support the overhead wires. The function of the cross arm The cross arm is an important part of the utility pole. Support wires and lightning protection wires, and keep them at a certain safe distance according to regulations.

Fasteners (bolts and nuts) can be divided into high-strength fasteners and ordinary-strength fasteners according to different strengths. The ordinary strength is generally grade 4.8, and the high-strength is generally grade 8.8, 10.9 and 12.9. Electrical fasteners are generally hot-dip galvanized on the surface.

"JECSANY" Power Line Hardware have stable quality and the products are exported to Southeast Asia, South Africa, South America, the Middle East and other global markets. OEM customization can also be made according to the drawings or samples provided by customers.
