Problems solved by technology

Ceramic and glass insulators are easy to be brittle and polluted, which can easily cause high-voltage flashover and broken bottles; the mandrel of ordinary rod-shaped composite insulators has poor bending resistance and is easy to be brittle
[0003] The end attachment of the insulator is the fixed part of the connection between the insulator and the transmission line and utility pole. It not only has to bear various external forces in the system and the pressure generated by the wire itself, but also bears the wind force of uncertain direction and snow accumulation during long-term use. Therefore, the connection quality between the end fittings and the mandrel is an important sign directly related to the safety and reliability of the product operation. Usually, the connection technology between the mandrel and the end fittings produced by the crimping assembly process is prone to brittle cracks , easy to loose, aging, and poor stability, there are potential safety hazards

Embodiment Construction

[0019] A suspension composite insulator, comprising a mandrel 1, a shed shed 2 arranged outside the mandrel 1, and components 3 arranged at both ends of the mandrel 1, the mandrel 1 is made of oriented glass fiber as a reinforced main material, and then passed through Soft insulating rubber material or flexible plastic is used as adhesive to bond into rods.

[0020] The shed shed 2 is made of polymer insulating material, which can be silicone rubber, EPDM rubber or soft plastic, etc. The shed shed 2 has the functions of protecting the mandrel, increasing the creepage distance, and resisting pollution , can be made into various shapes according to the pressure resistance and pollution resistance level, as shown in Figure 1, the shed shed 2 is sleeved on the mandrel 1, as shown in Figure 2, the shed shed 2 is integrally molded on the mandrel 1 superior.

[0021] As shown in Figure 3-4, the taper sleeve 4, the flared cone 5, the lock nut 6 and the connecting piece 7 constitute t...

Abstract

The related hang-type composite insulator comprises the mandrel with outside umbrella-skirt sheath and end members. Wherein, it uses the orientated glass fiber as mandrel reinforced body material, and applies soft insulation rubber or plastics to bond the mandrel. This invention has well reliability and smudges resistance, and can prolong service time greatly.

Description

technical field [0001] The invention relates to a composite insulator for power lines or electrified railway lines, in particular to a suspension composite insulator. Background technique [0002] Insulators are generally made of insulator materials with extremely high resistance. Its function is to separate conductors with different potentials, prevent the current from passing between the conductors, and enable the current to flow in a certain direction. At present, suspension insulators at home and abroad are divided into ceramic insulators, glass insulators, and composite insulators. Ceramic and glass insulators are easy to be brittle and polluted, which can easily cause high-voltage flashover and broken bottles; the mandrel of ordinary rod-shaped composite insulators has poor bending resistance and is easy to be brittle. [0003] The end attachment of the insulator is the fixed part of the connection between the insulator and the transmission line and the utility pole. ...
