Polymeric GOAB Switch and Polymeric DO Fuse

Polymeric GOAB Switch and Polymeric DO Fuse​

The manufacturing of a gang operating air brake switch with a polymeric insulator is done by using top graded raw material. These are three-phase switches and are used outdoor only. This product is used for separating the transformer from the distribution network. 

Polymeric GOAB switches are manufactured by using the highly conductive copper alloy that helps in providing high continuity to electricity. Many in-house tests are being performed by various companies on these GOAB switches for meeting the required standards. These tests include the following:

  • Power Frequency Voltage Dry Test

  • Measurement of resistance of the main circuit

  • Test to prove satisfactory operation

  • Dimensional Check

  • Galvanization test

  • Temperature Rise test

These GOAB switches are also being type tested for various types of tests. These type tests include the following tests:

  • High Voltage Dry and Wet Power Frequency Withstand Test

  • Lightning Impulse voltage withstand the test

  • Short time and peak withstand current test set

  • Temperature rise test

  • contact resistance test

  • Mechanical Endurance test

Here some of the common features of these switches:

  • These switches come with a light weight design and effortless handling.

  • The Polymer GOAB switch comes with the feature of perfect moisture-proof due to the usage of injection molding.

  • Another interesting feature of this product is its excellent durability and optimal structure.

  • These switches come with unlimited shelf life and corrosion resistance.

  • Also, they have excellent shock resistance features.

  • Polymer GOAB switches are affordable, user-friendly, and comes with effortless installation.

Polymer Drop out fuse

The Polymer Drop out fuse (DO) is used in the distribution system for protecting transformer centers tap lines and H T lines from over-load, breaking/making load current, and short circuit. Silicone rubber is used for designing fuse circuits due to which these switches can withstand the extremely stressful & cold environment along highly heated conditions in highly polluted locations or sea coasts.

This polymer drop out fuse is used in stopping the faults and they are very useful in using as the secondary backup unit for proving protection and security to the system. These switches must of type D or explosion type and outdoor lift-off type and perfect for operations that are done manually by an operating rod from the ground level. These switches are perfectly suitable for the distribution system from 11 KV to 33 KV.

Following are the features of these switches:

  • The installation of polymer drop out fuse is quick and effortless.

  • There is no need for any maintenance in these switches.

  • The certified plants for manufacturing these switches are ISO 9001 and 14001.

  • These switches are suitable for sea coasts and polluted environments.

  • Another feature of these switches include properties of long term surface hydrophobic.
