Aisatic Electrical Switch Gear Pvt. Ltd.

Naraina, Delhi

The Gang operated load break switches are meant for outdoor application and are suitable for horizontal or vertical mounting. They are designed for satisfactory performance in harsh atmospheric conditions of high/low temperatures & humidity. Their primary function is to isolate a 33kV, 3 Phase network.

FEATURES

* Single break type with 2/3 post insulators per pole. Quick make & break manual operation.

* Suitable for operation upto a altitude of 3000 m.

* Suitable for mounting at the top of a single or double steel pole.

* Used for single / three phase applications and suitable for operation on structures 6 meters or more above ground level with a pad lock facility.

* Robust sturdy design with bottom MS channel of adequate dimensions which imparts requisite strength.

* Copper contacts are made of ETP grade high conductivity copper and are spring loaded for adequate contact pressure. The contacts are duly plated to improve resistance to corrosion and offers a low resistance current path.

* All MS parts and Hardware are duly hot dip galvanized as per standard specifications which imparts long life to the switch.

* The Isolator is capable of withstanding the electrical & mechanical stresses induced during unlikely event of a short circuit.

* Sturdy operating mechanism is provided allowing easy operation 6 meters or above ground level with simultaneous operation of all the three poles making perfect electrical contact. Mechanical locking facility is provided for closed & open positions as required.

* The Post insulators are with min. creepage distance of 1150 mm suitable for heavily polluted atmosphere and meets the stringent requirements of IEC.

* The operating GI pipe provided along with the switch conforms to Medium Class as per IS 1239-1/ Eqvl and is 6000 mm in length.

* A choice of terminations can be provided to suit individual customer requirements.

The Surge Arrestors are an indispensable protection devise which needs to protect a transformer against natural lightning & switching surges in a high voltage system. They are designed for satisfactory performance in critical atmospheric conditions of high/low temperatures & humidity. Asiatic offers the latest Gap less Metal oxide technology which is far superior than conventional systems being used previously in terms of vast improvement in VA curves & increased through current capability at over voltages. Features

• The heart centre of the Surge Arrestor is a highly non-linear Zinc oxide discs also called Varistor capable of withstanding the surges.
• Housed in non-porous Porcelain or Silicone rubber housing along with other circuitry duly sealed.
• During passage of an electrical surges, the zinc discs allows the entire energy to earth by posing a very low resistance & instantaneously recovers to its original insulation property after passage of surge , getting ready for the next operation.
• Robust sturdy design in Porcelain housing with top Aluminium casted cap & bottom copper cap which totally seals the mechanism inside.
• The Surge Arrestor in Silicone rubber is comparatively light weight & UN-breakable, hydro phobic, resistant to UV rays, chemicals, ozone & corona. Further it offers excellent resistance to ageing under climatic conditions, electrical stresses & exhibits non-combustible properties.
• Can withstand rough handling or shipping. Reduced weight offers easy transportation.
• Both Porcelain & Silicone rubber arrestors can be supplied with mounting brackets.
• The flexible, thin sheds in Silicone rubber makes it possible to achieve highest creep age distances in comparatively shorter housing. In an unlikely event of a failure of a Surge arrestor due to excessive surges, porcelain housing may crack or burst in all directions but silicone rubber insulator may merely split open thereby preventing vandalism and damage to the adjacent equipments.
• The optional disconnecter can also be supplied which helps to disconnect ground lead from arrestor to avoid supply interruption & violent shattering of arrestor.
