Why Polymer Composite Insulators Excel over Traditional Glass Insulators

The materials used for insulating transmission equipment are nowadays made of specialty polymers. Ceramics or glass was utilized for this purpose in the past. These polymeric insulators would only be found in specified urban settings earlier, to protect them from getting polluted as well as acts of sabotage. However, these insulators are known as composite insulators and currently employed at nearly all power levels. S&E Specialty Polymers Company is among the reliable manufacturing firms that service the market for polymeric insulators. These polymeric insulators have a variety of benefits.


Polymer insulators, unlike traditional glass versions are very compact and light in weight. This enables them attain easy fitting into smaller cranes, apart from providing improved clearance space in-between ground and conductor. They are installed and maintained easily due to their lightweight nature. Manufacturers of polymeric insulators can obtain useful information on specialty polymers by visiting a website like http://www.sespoly.com/.


These gadgets by nature exhibit high water-resistance. Their hydrophobic properties keep water from accumulating on the insulator-surface, in turn preventing flashovers and surface currents. The S&E Specialty Polymers Company for instance ensures producing high-quality raw materials that meet such requirements for polymeric insulators.

Higher Mechanical Strength

Insulators made using specialty polymers such as those displayed on the S&E Specialty Polymers Website, possess phenomenal mechanical strength. Transmission towers can be sited when located at far off distances for this reason. The traditional insulators normally have low mechanical strength, which limits the capacity of transmission for the tower along with power productivity. It is easier covering larger areas without impacting productivity, using such devices. Visit at: S&E Specialty Polymers


Polymer insulators are resistant to pollution naturally, which is among their most strategic benefits. This quality helps them keep away dust, dirt and water, assuring that no malfunction, internal damages or external damages occur. The cost involved in cleaning and maintaining these gadgets is appreciably low as a consequence. Polymer insulators are suitable for use in areas having higher levels of pollution, along with where undertaking regular maintenance for them is not feasible.

Polymer Insulators are Reliable

Reliability of a gadget is among the most crucial aspects that one should consider during the purchasing process, whether acquiring composite or ceramic insulator. This factor is guided by its electrical and mechanical properties, which for instance are among the qualities exhibited by products displayed on S&E specialty polymers company website. Hi-tech fixtures and modern manufacturing techniques have facilitated manufacturers of composite insulators to improve the mechanical strength of their in a great way.

Advanced composite gadgets were introduced into the market several decades ago. They feature a structure which looks like a rod and is sealed with specific weather-resistant materials, normally fillers and rubbers. The end fittings then become fitted to the assembly in whole. The gap, interface or clearance between air and solid body is among the most crucial considerations for these insulators.

The main problem most times appears at the interface, since air and the solid insulator have the tendency of holding up at this spot. The negative effects of pollution, dirt and water accumulation lead to leakage in current supply, worsening overall installation-performance. As such for composite polymer insulators, the interior section of polyester core rod gets covered with heavy duty materials from manufacturers like S&E specialty polymers company, to improve efficiency and performance.
