Rashtriya Electrical is a well renowned company and is indulge in the businesss of over-head line insulator form 1969.
We are anapproved vendor in most Discom's in Indiaalso supplied material in different part of Africa.
Polymer Pin insulator, Composite pin insulator, Silicon Pin Insulators are different names for Polymer Pin insulator .These are used in Power Distribution System for 11kv and 33kv. Bottom part of the pin insulator i.e spindle is attached to the pole and the head of the insulator holds the conductor.

Porcelain Versus Polymer Insulator:
Depending on the application, it may be more prudent to choose either a Porcelain Pin Insulator or a polymer insulator. Please use the charts below to compare the different types of insulators:
Porcelain Insulator AdvantagesPorcelain 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
Polymer Insulator AdvantagesPolymer 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
Strong in tension
More susceptible to damage from arcing or flash overs
Less experience in the field, still changing as more polymer products come out
Harder to check for inconsistencies or damages
Dry arc distance is lower
Interface bonding issues
Weaker in compression
Electric network in India operates under very harsh environments. Industrial pollution, marshy land, hilly and unfriendly terrain, extreme weather, coastal region etc. make insulator contamination flash overs the main concern to the electric utility. Variety of solutions were tried to combat the insulator pollution flash over. Initially Ceramic Silicon Insulators,wholesale composite insulator, wholesales polymer insulator,silicone composite insulators,polymer post insulator,silicone insulator,polymeric insulator,composite polymer insulator,suspension composite insulator,wholesale composite insulator,disc suspension insulator,pin type insulator,polymer insulators manufacturers ,were in use and then the glass insulators were put to use, but these did not serve the flash over issue. The introduction of Composite Insulators(Polymer Insulators) OR Silicone Insulators was a turning point in the 1970s.
These silicone rubber insulators/composite insulators were popular for their pollution resistance and were useful ever in severe/harsh weather conditions. The composite insulators have distinctively hydrophobic surface and are resistant to chemical influence, weathering, UV radiation. The physio chemical and mechanical properties of these rubber composite insulators remain constant over wide temperature range. Hence there are negligible changes in the properties of polymer insulation and no electrical or mechanical failures are experienced.
Composite insulators we offer can be custom specified, manufactured, tested and are reliable for their service life. They are ideal for use in HVAC, HVDC and in most HV application.

We manufacture high voltage insulator 10kv-500kv series composite insulators, also known as polymer 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 dies insulator, polymer lighting arresster.
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.
