Surge Arrester

Low And Medium Voltage

 Raychem offers surge arresters for medium voltage power distribution systems that are designed to reliably protect your valuable assets from overvoltage. They can withstand severe outdoor exposure over long operating lifetimes and help maintain service reliability in both overhead and underground installations. Raychem arresters have passed the most rigorous tests (IEC 60099-4, ANSI C62.11, IEC 61643).

Low Residual Voltage – High Energy Absorption Capacity

The metal oxide varistors used in the arresters provide high energy absorption and low residual voltages. Multiple high current lightning and long duration switching surges are absorbed without noticeable changes in the arrester characteristics or stability.

• Outdoor applications
• Indoor applications (gas-insulated switchgears, busbars)
• Motor and generator protection
• Special applications (HV cable sheath and current limiting arcing horns for covered conductor systems)
• Low voltage distribution systems
• AC/DC railway applications

High Voltage

We provide a wide range of porcelain and polymeric transmission/substation surge arresters for applications up to 800 kV. The Bowthorpe EMP range of arresters has demonstrated reliable performance in environments all over the world for over 60 years.

•  Transmission line arrester.
•  Modular series parallel polymeric surge arrester.
•  Modular single column polymeric surge arrester.
•  Polymeric housed surge arrester.
•  Porcelain housed surge arrester.

Our competence in materials science is fundamental to our ability to design polymeric insulators that more than meet application requirements even for severe environments. We have worked closely with customers to optimize the design and installation of our products in some of the most challenging environments in the world. Polymeric insulators are based on our 35 years of rich experience in the field of crosslinked polymers for medium- and high-voltage applications. They consist of a polymeric housing over a pultruded fibre glass rod to which galvanized steel or aluminum end fittings are attached.

Housing materials in either ethylene vinyl acetate (EVA) or silicone are available depending on customer preference and application.

Products Range:

• Line post Insulators
• Station post Insulators
• Suspension & Tension insulators
• Hybrid post Insulators
• Hollowcore Insulators
• Railway Insulators

Indian state utilities are striving hard to come out of the red and are now aggressively investing in upgrading and strengthening the medium voltage (MV) and low voltage (LV) distribution system.

At Raychem RPG, we have identified this need of profiling the electricity losses with each utility and taking a customised approach to reduce the same. Distribution losses are attributed to three major factors, technical, societal and commercial losses.
Raychem RPG has been instrumental in developing several innovative technologies to address the issues in the Indian distribution system to Reduce losses and Maximize Profits for Indian Distribution utilities.

In our yet another endeavour for the cause, Covered Conductors have been introduced for the first time in India by Raychem RPG for applications up to 132 kV in partnership with amokabel, a Scandinavian group company and leading producer of different types of covered conductors for varied applications.

Covered Conductors are longitudinally water blocked and covered with special grades of materials that provide insulation and ultra violet protection. These conductors provide safety against accidental contact and are a major help in significantly reducing outages.

Covered Conductors have been type tested up to 66kV in line with EN50397 at CPRI and also at International labs.

Insulation enhancement systems for substations and overhead lines.Designed to prevent unplanned outages due to accidental bridging and to help upgrade insulation levels at critical points in systems.

By insulating strategic areas it is possible to eliminate such problems and in areas of growing environmental awareness, such as the protection of endangered species, our insulation products will allow wildlife to come and go without danger of being electrocuted.
