Porcelain insulators are insulators made of electrical ceramics as insulation components. Electrical ceramics are baked from quartz, feldspar, and clay as raw materials. The surface of porcelain insulators is usually covered with porcelain glaze to improve their mechanical strength, prevent water infiltration, and increase surface smoothness.
Zinc oxide lightning arrester is a lightning arrester with good protective performance. Utilizing the excellent nonlinear volt-ampere characteristics of zinc oxide, the current flowing through the lightning arrester at normal operating voltage is extremely small (microampere or milliampere level); When overvoltage occurs, the resistance drops sharply, releasing the energy of overvoltage to achieve protection.
Suspension clamp is a hardware device that suspends the grounding wire to the suspension insulator string or hardware string.The body is made of UV resistant,glass fiber reinforced synthetic material.The insulated neutral messager is secured by the notched tightening lever.It is used for suspending the low voltage A.B.C.(Aerial bundled conductors)
Preformed Guy Grips is a common metal product mainly used in industries such as electrical equipment, communication equipment, and mechanical equipment. According to their different materials, structures, and uses, Preformed Guy Grips can be classified into various types.
Fuse Link in the circuit system mainly serve as overload protection. If the fuse Link is correctly placed in the circuit, it will fuse Link and cut off the current when the current abnormally rises to a certain height and heat, protecting the safe operation of the circuit
Terminals refer to wiring terminals, also known as wiring terminals, which can be classified into single hole, double hole, socket, hook, etc. In terms of materials, they can be silver plated copper, zinc plated copper, copper, aluminum, iron, etc. Their main function is to transmit electrical signals or conduct electricity.
Bolted copper lugs are widely used for secure cable-to-equipment connections, offering high conductivity and excellent mechanical strength for easy installation and maintenance.
Zinc oxide surge arrester is a lightning protection device with superior protection performance, light weight, pollution resistance and stable performance. It mainly uses the good non-linear volt-ampere characteristics of zinc oxide to make the current flowing through the surge arrester at normal working voltage very small (microamp or milliampere level); when the overvoltage acts, the resistance drops sharply, venting the overvoltage Energy to achieve the effect of protection. The difference between this kind of lightning arrester and the traditional lightning arrester is that it has no discharge gap, and uses the non-linear characteristics of zinc oxide to discharge and break.
Zinc oxide lightning arrester is a lightning arrester with good protective performance. By utilizing the excellent nonlinear volt ampere characteristics of zinc oxide, the current flowing through the lightning arrester at normal operating voltage is minimized; When overvoltage occurs, the resistance drops sharply, releasing the energy of the overvoltage to achieve protection.
The galvanized single steel wires or stranded steel wires are suitable for cores of ACSR to improve its tensile strength. And they can also be used in the aerial transmission line as the line material of ground connection to avoid the lightning strike. Messenger Wire, Overhead Ground or Static Wire, Guy Wire.
Low-voltage ABC cable, designed for overhead power lines and room entrance wires with a rated AC pressure of 1kv and below. It has less installation, maintenance, and operating costs, which can achieve greater economic loss and provide higher security and reliability.
Dead end guy grips, installed at the top, the breaker and the anchor, provide today's most effective method for
securing guy strand. This unique, one-piece dead-end is neat in appearance and free from bolts or high-stress
holding devices. The dead end guy grips was the first to offer the cabled loop, a feature that provides more
durability, easier tensioning and adaptability to multiple guying.
Dead end guy grips are made of the same material as the strand to which they are applied. They should be used
on hardware that is held in a fixed position. The fitting should not be allowed to rotate or spin about the axis of the
strand. They should not be used as tools; that is, come-along, pulling-in grips, etc.

Cable Line Accessories
Power cable accessories are products that connect cables to transmission and distribution lines and related distribution devices. They generally refer to the intermediate and terminal connections of various cables in the cable line, and together with the cables, they form the power transmission network; Cable accessories are mainly based on the characteristics of the cable structure, which can restore the performance of the cable while ensuring the extension of cable length and terminal connection.
Insulation piecring connector prooerty:It is mainly used for branch connection,succession and grounding protection for 20kV,10kV and 1kV or below: 1.Simple installation:Put the main wire and the branch wire directly on the right place without wire stripping.Tighten the shear head evenly by wrench. 2.Low resistance and low temperature-rise:The spcial bolts can ensure equal piercing pressure for superior electric contact and less wire damage,so that make sure the normal service life of the pierced wire. 3.Sealing structure with good insulation:tight insulated lining and enough compound to ensure the insulation function in good control when connector used outdoors.
