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.
