33 KV Gang Operated Load Break Switch

The 33 KV Gang Operated Load Break Switches are meant for outdoor application. These switches are suitable for horizontal or vertical mounting. These switches are manufactured to control the electrical supply in industrial and commercial sector. It is used for electrical operations and power distribution. These breakers are tested by our quality controller on different quality parameters before delivering to our valued customer ends. Our offered 33 KV Gang Operated Load Break Switch is 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 an altitude of 3000 m and mounting at the top of a single or double steel pole.
• It should be equipped on structures 6 meters or more above ground level with a pad lock facility.
• Copper contacts are made of ETP grade high conductivity copper. It also has a spring loaded for adequate contact pressure.
• The MS parts and Hardware are duly hot dip galvanized as per standard specifications which imparts long life to the switch.
• It can withstand the electrical & mechanical stresses induced during unlikely event of a short circuit.
• 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.
