Composite Insulators Manufacturers

Composite Insulators Manufacturers

We manufacture high voltage insulator 10kv-500kv series composite insulators, also known as Composite insulators or silicone rubber insulators, which include suspension long rod silicone rubber insulators, pin type composite insulators, station post polymer insulators, cross arm silicone rubber insulators, electrified railway polymer insulators, Polymer dise insulator, polymer lighting arrester.

Composite Insulators

As the replacement of porcelain insulators, silicone rubber composite insulators have many advantages:
  • 1. Excellent anti-pollution performance, suitable for high polluted area
  • 2. Free of cleaning, economical maintenance and suitable for difficult maintenance area
  • 3. No need of zero value check
  • 4. Light weight, easy and economical to transportation and installation
  • 5. Not brittle, and reduce the purchasing quantities for spare parts.

Line Post Insulator

We offer an deal in wide range of Electrical Line Post Insulator 11kv, 22kv, 33kv, 66kv, 132kv Line Post Insulator used on distribution line and transmission line upto 132KV. It is mounted rigidly on supporting structure by means of a steed or bolts. It is non-puncturable design. Connected fitting type: tie top conductor binding type and clamp top with vertical or horizontal mounting.

Depending on the application, it may be more prudent to choose either a porcelain insulator or a polymer insulator.

Please use the charts below to compare the different types of insulators:

Porcelain Insulator Advantages Porcelain Insulator Disadvantages
  • Very long life, made of inorganic materials and do not age.
  • Very reliable, with a proven track record. Over 80 years of experience
  • Have higher leakage distance profiles
  • Easier to maintain, can be coated and washed
  • Have more flexibility in length with more units
  • Easy to identify a damaged unit
  • Strong in compression
  • Heavy, leading to more expensive shipping and more difficult handling
  • Could have hidden defects that are hard to detect
  • Vandalism is common from thrown rocks, or from being shot at
  • Pin erosion, and coupling hardware corrosion
  • Cement growth cracking
  • Weaker in tension
  • Porcelain Insulator Advantages Porcelain Insulator Disadvantages
  • Lighter in weight, almost a 90% weight reduction. This weight reduction leads to easier handling, reduced shipping and installation costs.
  • Better performance in high contamination areas
  • Overall better handling of shock loads
  • More aesthetically pleasing the eye, and smaller profile
  • More resistant to vandalism and breakage due to the forgiving nature of polymer
  • Easy to identify a damaged unit
  • Strong in tension
  • More susceptible to damage from arcing or flashovers
  • Less experience in the field, still changing as more polymer products come out
  • Harder to check for inconsistencies or damages
  • Dimensions vary
  • Storage concerns
  • Dry arc distance is lower
  • Interface bonding issues
  • Weaker in compression
