GOST material clauses that general suppliers will not commit to
What Gets In The Way
- GOST material clauses that general suppliers will not commit to
- Threaded cubicle seats that flange-mount post insulators will not fit
- Wall penetrations that have to be insulated and sealed at the same time
- Post insulators flexing under busbar short-circuit forces
What This Sector Needs From A Supplier
- Post insulators with published cantilever and torsion ratings
- GOST ceramic, fitting alloy and bonding cement clauses met by specification
- Round and oval flange wall bushings to match existing openings
- Indoor bushings with a stated bearing capacity

Product Families To Start From
Post Insulators
Solid core post insulators supporting live parts in switchgear and on line supports, in GOST and threaded patterns.
Wall Bushings And Other Insulators
Through-wall bushings, indoor bushing insulators and GOST pattern parts that fall outside the main transformer bushing families.
Where These Parts End Up
- Busbar supports inside distribution switchgear cubicles
- Disconnector and circuit breaker operating shaft supports
- Enclosed distribution devices at power stations and substations
- Package substations connecting to outdoor switchyards

Switchgear Manufacturers Questions
Guides For This Sector
Low Voltage Post Insulators Principles Applications And Selection
A low voltage post insulator has to do two things at once: stop the current and carry the load. Getting the selection right means
What Is A High Voltage Transformer Insulator
The high voltage transformer insulator is a physical barrier isolating the high voltage parts of a transformer from the lower volt
