Power Line Hardware & Accessories
Power line hardware is the building blocks for any power and communication project, including surge arresters, overhead line connectors, power line insulators, utility fasteners, and more. These components assure the free passage of electricity and signal while protecting people and animals passing by. They also facilitate maintenance activities in harsh environment, improving efficiency and safety. Hardware components manufactured in accordance with international standards ensures quality and usability in various regions.
Fuse Cutout
A fuse cutout is an electrical protection device used in primary overhead feeder lines and taps to protect distribution transformers from current surges and overloads.
11-38kV Expulsion Fuse Cutout for electrical distribution
Overview:
In electrical distribution, a fuse cutout or cut-out fuse (often referred to as a cutout) is a combination of a fuse and a switch, used in primary overhead feeder lines and taps to protect distribution transformers from current surges and overloads. An overcurrent caused by a fault in the transformer or customer circuit will cause the fuse to melt and the switch mechanism to visibly open, disconnecting the transformer from the line. The device can also be opened manually by utility linemen standing on the ground and using a long insulating stick called a "hot stick".
Product categories

Composite insulator
A composite insulator, also called a dielectric or nonconductor, is a material that resists the flow of electric current. This type of silicone rubber material is used in parts of electrical equipment intended to support or separate electrical conductors without passing current through itself. In power systems generally refers to insulating supports that attach electric power transmission wires to utility poles or pylons.Composite insulators are less costly, lighter in weight, and have excellent hydrophobic capability. This combination makes them ideal for service in polluted areas. However, these materials do not yet have the long-term proven service life of glass and porcelain.
Surge Arrester
Surge arrester is also called overvoltage protector and overvoltage limiter. It is connected in parallel to the front end of the protected equipment to protect other electrical equipment from lightning overvoltage, operating overvoltage and power frequency transient overvoltage impact.Surge arrester in AC distribution system, it is also called a distribution arrester, which is mainly used to protect distribution transformers, cables and power station equipment.
Surge arresters are installed on circuit breakers inside a residential home, inside pad mounted transformers, on pole mounted transformers, on pole-mounted riser poles and substations.
Gapless Metal Oxide Surge Arrester (MOSA) for electric power systems
Overview:
Gapless Metal Oxide Surge Arrester which uses zinc oxide semiconductor as a resistor material, such type of arrester is known as a metal oxide surge arrester or ZnO Diverter. This arrester provides protection against all types of AC and DC over voltages. It is mainly used for overvoltage protection at all voltage levels in a power system.
Overhead Line Fittings
Overhead line fittings are also called overhead line fittings or overhead line accessories. Overhead line fittings include various steel fittings used to construct overhead lines, used for hanging, fixing, protecting, connecting, connecting overhead lines or insulators on overhead lines and the metal device used to connect the cable on the cable structure of the cable tower is an important part of the circuit transmission hardware, which ensures the stability of the transmission line.
