High Voltage Disconnectors are designed, manufactured and tested in Australia by Insulect, to meet individual customer requirements.
Available for 12kV, 24kV, 36kV, 72.5kV and 145kV.
Tailor-made solutions adapted to specific substation layout requirements.
Customised to suit specific substation layouts, configurations and structure types.
Insulect Disconnectors are designed to accommodate each customer’s needs and the layout of each substation.
For over two decades, our disconnector and earthing switches have been 100% locally designed, built and serviced to ensure the best possible solution tailored to the needs of our customers.

MOTOR DRIVE FOR SUBSTATION DISCONNECTORS
For many applications it is desirable to operate switches remotely.
A motor drive eliminates the need for manual operation of disconnectors and earth switches and will enable operation when it is not safe to have a man in the switch yard.
It also enables disconnectors and earth switches located at remote or unmanned sites to be operated from a remote control room when there are no local personnel available.
- IP65 rated stainless steel cabinet.
- Variable speed DC motor.
- The control voltage can be specified as AC or DC.
- Limit switches coupled with mechanical stops prevent the output shaft over-rotating and damaging the contacts.
- Protection is provided for the motor by fuses and thermal overload devices.
- An anti-condensation heater prevents moisture build-up inside the cabinet.
- Positioning and mounting of motor drive components can be customised to suit user requirements.
Each disconnector can be fitted with independent earth switches where required.
Earth switches can be supplied for one or both sides of the switch.
The mechanism for each switch can be fitted with Auxiliary Switches to enable a substation control system to monitor the state of the disconnectors and earth switches.
Auxiliary switches can be supplied with more than 12 poles, depending on the control information required.
Mechanical or electrical interlocks can be provided for all disconnector models.
Mechanical interlocks prevent the earth switch operating when the disconnector is in the ‘closed’ position and vice-versa.
Electrical interlocks can be provided for disconnectors and earth switches that are fitted with a motor drive. It prevents the motor drive from engaging unless it is safe to do so.
INSTALLATION AND REFURBISHMENT SERVICES
Insulect provides refurbishment and retrofit solutions for disconnectors and their contacts. Our services range from refurbishment of existing contacts, retrofit of new contacts on existing Disconnectors. We can also supply a new disconnector to suit existing structure or a complete replacement solution to suit existing footings.
