High voltage line rigid insulators include needle type porcelain insulators, porcelain cross arm insulators, and butterfly type porcelain insulators. When in use, they are directly fixed to the tower with the steel feet or bolts of the insulator itself. According to the structural form, they can be divided into four types: all ceramic, adhesive, single arm, and V-shaped; According to the installation form, it can be divided into two types: upright and horizontal; According to the standard lightning impulse full wave withstand voltage, it can be divided into four levels: 165kV, 185kV, 250kV, and 265kV.

Butterfly porcelain insulators for high-voltage transmission lines are divided into two levels according to their rated voltage: 6kV and 10kV. They are used for overhead transmission and distribution line terminals, as well as for processing post insulators based on samples. They are also widely used for insulation and fixing wires on tension and corner poles. They are also widely used in conjunction with line suspension insulators to simplify hardware structures.

Dongguan Wanfu Hardware Products Co., Ltd. has nearly 50 gear production and processing equipment, with an annual output of about 10 million pieces. It passed the ISO9001:2000 quality management certification on January 9, 2006, and the ISO14001:2004 environmental management system on September 5, 2008. With excellent quality, fast delivery, and reasonable prices, our company has won customers from Japan, the United States, Germany, Hong Kong, Taiwan, and mainland China. The model parameters of our pillar insulators have been well received by customers.

The tension insulator string meets three requirements: no pollution flashover under working voltage, no wet flashover under operating overvoltage, sufficient insulation level for lightning impulse, and can ensure that the lightning resistance level and lightning trip rate of the line meet the specified requirements.

Select the type of suspension insulator to be used based on mechanical load and environmental conditions, choose the number of pieces in the string according to the leakage distance required by the working voltage, calculate the required number of pieces according to the operating overvoltage requirements, and verify whether the lightning resistance level and lightning trip rate of the line meet the specified requirements.

There are many types of insulators used in transmission lines, which are usually divided into breakdown type and non breakdown type according to insulation. According to the structural type of insulators, they can be divided into disc-shaped insulators and rod-shaped insulators. According to the insulation medium, they can be divided into porcelain insulators, glass insulators, semiconductor glazes, and composite insulators.

At the same time, insulators are divided into ball type and groove type insulators according to their connection methods, and into multiple levels of insulators such as 40kN, 60kN, 70, 100, 160, 210, 300kN, 420kN, 550kN, etc. according to their bearing capacity. According to the requirements of the usage environment, each type of insulator can be further divided into ordinary type, pollution resistant type, aerodynamic type, and spherical type insulators.

Dongguan Wanfu Hardware Products Co., Ltd. can provide customers with precision small and medium modulus gears, screws, worm gears, pulleys, precision shafts, shaft sleeves, etc. with a module of 0.2-2.0 and an outer diameter of 120mm or less.
