FPEG-12/5 type high-voltage lightning protection needle insulatorDetailed product description：

10KV transmission and distribution lines are the most commonly used voltage level lines in power systems. Due to the generally low insulation level of 10KV lines, they are difficult to withstand the effects of direct lightning strikes or induced lightning. Not only will they flashover and trip when lightning strikes the wires and tower tops, but also when lightning strikes surrounding trees or buildings, the induced voltage will be too high, causing flashover and insulation layer breakdown. The continuous power frequency arc will burn here, and the wires will be burned out in a very short time. At present, more and more 10KV distribution lines in major and medium-sized cities in China are using insulated conductors as overhead distribution lines, effectively solving the corridor and safety problems that are difficult to solve with bare conductors. Compared with underground cables, it has the advantages of low investment and fast construction. However, it also brings some new technical problems, one of which is lightning breakage during the operation of insulated conductors. Lightning breakage has become a safety problem faced by the power system. In order to address the shortcomings of existing technology, our company has newly developed lightning protection products such as FPEG-12 high-voltage lightning protection needle type composite insulators (divided into piercing and non piercing types). The above new products all have lightning protection function. These new lightning protection products have reliable performance, easy installation and construction, low investment, and high returns, providing a more economical, safe, and effective way for the power sector.

Product Introduction
FPEG-12 high-voltage line lightning protection needle type composite insulator (piercing/non piercing) is a new type of composite structure product, which not only has the function of ordinary needle insulators, but also plays the role of supporting wires and insulation; It also has the function of preventing lightning strikes. FPEG-12 high-voltage line lightning protection needle type composite insulator is a new type of lightning protection function combination structure used for two in one lightning protection insulation and supporting wires. It also has the protection function of preventing 10KV overhead insulated wires from lightning strikes and wire breakage. The installation and construction are convenient and reliable, and it greatly reduces the labor intensity of operators. Due to the integration of composite insulators and lightning protection clamps, the line is simplified and the cost is reduced. This product has reliable performance, low investment, and high returns, providing an economical and effective way for the power sector to prevent lightning strikes and wire breakage of 10KV overhead insulated wires, and has good promotion value.
2. Characteristics of FPEG-12 high-voltage line lightning protection needle type composite insulator
This product is ingeniously designed, easy and fast to install, and has good lightning protection effect.
2.1 Stable lightning discharge gap: It has a stable lightning discharge voltage, can locate the lightning impulse discharge path, and ensure that lightning occurs between lightning discharge gaps.
2.2 Secure and reliable wire clamp device: With a controllable penetrating outer insulation layer, it tightly and reliably contacts the wire, has good thermal stability, and can ensure the safe operation of overhead insulated wires.
2.3 High strength resistance to arc burning: Multiple times withstand arc burning, reliably dissipate power frequency arcs away from insulated wires and line insulators, and protect insulated wires from burns and wire breakage.
2.4 Easy and convenient installation: Directly installed to effectively prevent lightning strikes and wire breakage, equipped with insulation protective covers, the entire high-voltage electrode is wrapped in insulation covers, ensuring safe and reliable operation.
2.5 Composite insulators have better insulation performance than PS-15 and other electric porcelain insulators, and their creepage distance is larger, which improves the anti pollution level of insulators and can meet the anti pollution requirements of a large number of users for insulators.
2.6 The insulation shield is made of organic composite material, which has good insulation performance, anti-aging performance and flame retardant performance. It can be assembled outside the high-voltage electrode for insulation protection.
2.7 Unique structure to prevent birds from causing short circuit hazards to overhead wires.
4.8 Can withstand about 5 times of high current arc burning at power frequency.
