INSTALALTION:

The disconnectors and earthing switches are preassembled and adjusted at works, as complete as possible. The construction is designed so that all disconnectors can be installed and adjusted at site very easily, without the need of any special tools. Clear instruction manual and assembly drawing provided to ensure hassle free installation.

MAINTENANCE:

SGear Disconnectors are virtually maintenance free. However to ensure a long and trouble free service period, a visual inspection of contacts and bearing points can be carried out at intervals.

MAIN CONTACT:

The main contact consists of two fixed contacts mounted on support insulators on both ends and a moving blade in between that contacts that is hinged on one of the fixed contacts.

The fixed contacts are made out of hard drawn electrolytic copper duly silver plated and are of reverse design supported by stainless steel springs.

The moving contact is designed to cross dead center in the open and close position enabling reliable operation.

The dead center interlocking of operating mechanisms ensures there are no inadvertent changes in the open or close switching position even under extreme external conditions such as storms, earthquakes etc.

HIGH VELOCITY CONTACTS:

SGear railway disconnectors are provided with high velocity arcing contacts to enabling breaking of charging currents. The spring assisted high velocity contacts are make before and break after contacts, protecting the main contacts.

OPERATING MECHANISM:

The drive mechanism is enclosed in aluminium or stainless steel cubicle with robust gear mechanism to endure more that 10,000 operations.

The operating mechanism also houses the auxiliary contacts for position indication and interlocking.

TESTING:

The disconnector and earthing switches are designed and tested in accordance with latest IEC specifications. Quality Management systems is being maintained according to ISO:9001:2018
