Product characteristics
- Made of toughened glass. Because of the high mechanical strength of
the glass insulator surface, it is not easy to crack the surface.
The electrical strength of glass generally remains constant
throughout the operation period, and the aging process of glass is
much slower than that of porcelain.
- Using glass insulator, it can cancel the operation process of
insulator of charged periodic preventive test. This is due to every
damage to tempered glass causes damage to the insulator, which
operators can easily find when patrolling the wire.
- Insulator is a special insulation control, which can play an
important role in overhead transmission lines.
- In the early years, insulators were mostly used in poles, and
gradually developed into high-voltage wire towers with a number of
disc-shaped insulators hanging at one end. They were made of glass
or ceramics to increase the creeping distance.
- Insulators should not fail due to various mechanical and electrical
stresses caused by changes in the environment and electrical load
conditions, otherwise insulators will not play a significant role,
which will damage the service life of the entire line.
