Ranking among the top manufacturers of composite polymer insulators, Compaq International is a popular company, which manufactures medium and high voltage composite polymer insulators like Composite silicone insulators , Polymer line Post Insulators. The insulators we design include pin type composite insulators, suspension long rod silicone rubber insulators, station post polymer insulators, cross arm silicone rubber insulators, Polymer disc insulator, electrified railway polymer insulators and etc. Our Polymer Insulators are manufactured to cater to application requirements even for severe environments. They come with a polymeric housing over, which is a pultruded fiber glass rod. An aluminum end fittings or galvanized steel are attached to this glass rod. Based on customers’ needs and application requirements, Compaq International also provides them with housing materials in silicone or ethylene vinyl acetate (EVA)

We offer an deal in wide range of Polymer Disc Insulators 11kv,33kv,66kv,132kv, T&c and B&S, 16mm and 20mm ball pin.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 dise insulator, polymer lighting arrester. As the replacement of porcelain insulators, silicon rubber composite insulators have many advantages:  Excellent anti-pollution performance, suitable for high polluted area Free of cleaning, economical maintenance and suitable for difficult maintenance area No need of zero value check Light weight, easy and economical to transportation and installation Not brittle, and reduce the purchasing quantities for spare parts.

Ruled over the market till late second half of the 20th century. The polymeric insulator has a fiber rod structure covered with weather resistant rubbers and fillers and fitted with end fittings. Such a type of insulator is also called composite insulator. The most critical thing to be considered in outdoor insulators is the interface between the solid insulting body and the surrounding air. The problem appears at the interface because it is the interfering point of air and the solid insulator. This problem arises due to the effects of pollution, rain, dust, salt, corona, arcing over surfaces, nitric acid in air, etc. These things increase the leakage current and deteriorate its performance. Surfaces of insulating bodies were therefore coated with glazed material for glass and porcelain insulators, and organic or semi-organic polymer rubbers for composite insulators. A typical composite insulator is composed of a glass fiber reinforced (GFR) epoxy or polyester core (rod), attached with metal end-fittings. This is the load bearing structure. GFR plastics are mechanically very strong but are not able to bear the outdoor environmental effects. The presence of dirt and moisture in combination with electrical stress causes the material to degrade by tracking and erosion. So the rod is covered by a coating that protects it from outside stresses such as rain, salt, fog, pollution, etc. This coating is referred to as housing. A housing material should be able to protect the load-bearing core and provide sufficient pollution with stand. The reason of use of rubbers instead of ordinary plastics is simply the fact that the housing must be flexible enough to follow the changes in dimension caused by temperature or mechanical load. The early developments of modern polymeric insulators started in 1964, and prototypes for field installations started in 1967, and a report from 1996 stated that insulators installed in 1969 were performing well.

The Polymer Insulators, offered by us, have the high mechanical strength and Easy installation. We are staffed with the most up to date machines and cutting-edge technology for the testing of raw material and thus, with without fail we carry out stern quality examinations of the same at the initial stages. Our company has all the necessary logistic resources and connection to make on time delivery of order(s).

We offer online and offline Payment Processing as per the needs of the customers; not just the transactions details, but we sternly keep the personal details confidential that is shared by our clients. We keep a stern check while the product is being developed to make sure that we deliver only flawless range.
