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.
- Insulator is a special insulation control, which can play an
important role in overhead transmission lines.
- In the early years, insulators were mostly used for utility
poles, and slowly developed from one end of the high voltage wire
connection tower to hang many disk-shaped insulators, which were
usually made of glass or ceramics to increase the distance of
climbing, and were called insulators.
- 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.
- Insulator is one of the key components of HV transmission
line, and its performance directly affects the operation safety of
the whole transmission line. Glass insulators are widely used
because of their zero-value self-breaking and easy maintenance.
