• Function: Provides operators with real time position feedback for voltage adjustment.

Disconnect Type Control Cable allows for easy connection and disconnection of control wiring.

• Location: Routed between the control enclosure and internal components.
• Layout: Fitted with quick disconnect connectors for simplified servicing.
• Function: Enables safe maintenance and replacement of control systems without full disassembly.

Service Handhole provides access to internal components for inspection and maintenance.

• Location: Positioned on the tank wall.
• Layout: Circular bolted cover with gasket sealing.
• Function: Allows technicians to access internal parts without removing major assemblies.

Ground Pads provide designated grounding connection points.

• Location: Welded to the external tank surface.
• Layout: Flat conductive pads with drilled holes for secure grounding connections.
• Function: Ensures proper grounding for safety and system stability.

Drain Valve allows for controlled removal of insulating oil.

• Location: Installed at the bottom of the tank.
• Layout: Threaded valve assembly designed for secure sealing.
• Function: Facilitates oil draining for maintenance, testing, or replacement.

Arrester Mounting Provisions provide structural support for surge arresters.

• Location: Located near bushing areas on the tank exterior.
• Layout: Reinforced mounting brackets or pads.
• Function: Ensures secure installation of arresters for effective surge protection.

Lifting Lugs are used for hoisting and positioning the regulator.

• Location: Welded to the top of the tank.
• Layout: Heavy duty steel loops designed for rigging attachment.
• Function: Allows safe lifting during transportation and installation.

Untanking Lifting Eyes assist in removing the internal assembly from the tank.

• Location: Attached to the internal core and coil assembly.
• Layout: Reinforced lifting points accessible during servicing.
• Function: Enables safe extraction of internal components for maintenance.

Automatic Pressure Relief Valve protects the tank from excessive internal pressure.

• Location: Mounted on the tank top or upper wall.
• Layout: Spring loaded valve designed for automatic operation.
• Function: Releases pressure during fault conditions to prevent tank rupture.

Oil Level Sight Gauge provides a visual indication of oil level inside the tank.

• Location: Mounted on the side of the tank.
• Layout: Transparent or dial type indicator calibrated for oil levels.
• Function: Allows quick verification of proper oil volume for safe operation.

Nameplates display critical product and operational information.

• Location: Attached to the exterior of the tank.
• Layout: Metal plates with engraved or printed specifications.
• Function: Provides identification, ratings, and compliance details for the regulator.

Substation Base supports the regulator and provides mounting stability.

• Location: Integrated at the bottom of the unit.
• Layout: Structural steel base designed for pad or foundation mounting.
• Function: Ensures secure installation and proper load distribution.

Upper Filter Press Connection allows connection to oil filtration equipment.

• Location: Positioned on the upper section of the tank.
• Layout: Threaded or flanged connection point.
• Function: Enables oil circulation and filtration during maintenance.

Cable Support provides structural support for connected cables.

• Location: Mounted near cable entry points.
• Layout: Brackets or clamps designed to hold and organize cables.
• Function: Reduces strain on connections and maintains proper cable routing.

Plate Type Cooling Radiators dissipate heat generated during operation.

• Location: Mounted externally on the tank sides.
• Layout: Flat plate assemblies that increase surface area for cooling.
• Function: Enhances heat transfer to maintain optimal operating temperature.

Thermometer Provision allows installation of temperature monitoring devices.

• Location: Installed on the tank top or upper wall.
• Layout: Fitted opening or well for thermometer insertion.
• Function: Enables monitoring of oil temperature to ensure safe operation.
