Crompton Greaves 615923 Porcelain Bushing 17.5 kV

Product Overview

The Crompton Greaves 615923 is a porcelain bushing rated for the 17.5 kV voltage class, manufactured for transformer applications. CG Power (Crompton Greaves) is a leading global manufacturer of power equipment including transformers and their associated components such as porcelain bushings.

This bushing provides the insulated electrical connection between the transformer winding and the external circuit, passing through the transformer tank wall. The porcelain insulator provides high dielectric strength and weather resistance, while the central conductor carries the rated current. It is suitable for use in oil-immersed distribution and power transformers.

Confirming the Correct Replacement Bushing

Transformer bushings that share a voltage class can still differ in current rating, creepage distance, conductor type, flange dimensions and terminal arrangement. Before ordering 615923, collect the following from the transformer and the failed bushing:

• Transformer rating plate: manufacturer, serial number, year, kVA rating and voltage ratio
• Any part number or marking cast or printed on the porcelain or flange
• Overall length, the length above and below the mounting flange, and the flange or clamping arrangement
• Stem thread size and terminal type, and whether it is a line or neutral position
• Clear photographs of the installed bushing and any damage

Comparing these details with the original design data is the reliable way to avoid a bushing that is electrically correct but does not physically fit.

Installation Guidance

• De-energize, isolate and earth the transformer, and lower the oil level only as far as needed to access the bushing.
• Inspect the new porcelain for chips or cracks before fitting, and handle it by the flange, not the sheds.
• Always fit new gaskets of the correct material and tighten flange bolts evenly in a cross pattern to avoid stressing the porcelain.
• Make the internal lead connection securely and check clearances to the tank and other leads.
• Top up with dry, tested transformer oil, then check for leaks and perform insulation resistance and ratio checks before re-energizing.

Inspection and Common Failure Causes

Routine visual inspection should look for oil leakage at the gasket, cracked or chipped sheds, surface tracking and heavy contamination. Thermal imaging under load is useful for finding overheated terminal connections, which are a frequent cause of bushing damage. In coastal and desert environments, salt and dust deposits reduce the effective creepage distance, so periodic cleaning of the porcelain helps prevent flashover.

Applications in Oman and the GCC

Replacement bushings in this voltage class are needed by utilities and distribution companies, industrial plants, oil and gas facilities and water utilities that operate distribution transformers across Oman and the region. Holding a spare shortens outage time after a flashover, vandalism or handling damage.
