Russia 10kV Wall Bushing Ceramic Insulator IOR-10-3.75 II UKhL2



Wall Bushings And Other Insulators
Product Overview
A GOST wall bushing for installing and insulating conductive parts in enclosed and complete distribution assemblies at power stations and substations, and for connecting them to open switchgear or transmission lines at up to 10 kV and 100 Hz. It is rated 630 A with an 80 kV lightning impulse test voltage, a 7.5 kN minimum bending failure force and a 300 mm leakage path, for atmosphere types I or II to GOST 15150-69.
Key benefits
Why Buyers Choose This Part
- 630 A rating at 10 kV through an enclosure wall
- 7.5 kN minimum bending failure force for externally loaded connections
- 300 mm leakage path on a compact indoor-to-outdoor penetration
- Classified for atmosphere types I and II under GOST 15150-69
Application scenarios
Where It Is Used
- Connecting enclosed distribution assemblies to an outdoor switchyard
- Complete distribution devices at power stations and substations
- Enclosed busbar runs passing through a barrier wall
- Switchroom refurbishment where the GOST designation must be matched
Who it is for
Who It Suits
- Switchgear manufacturers building complete distribution devices
- Power station and substation maintenance engineers
- Distributors supplying GOST wall bushings
Problems it solves
What Goes Wrong Without The Right Part
- Wall penetrations that have to be both insulated and mechanically sound
- Connections that bend the bushing when the outdoor conductor is tensioned
- GOST clauses that a general purpose bushing cannot be signed off against
- Leakage paths too short for the site atmosphere class

Comparison
How It Compares
| IPU-10/630-7.5 I UKhL1 | Same 10 kV, 630 A and 7.5 kN class. The IPU listing calls out construction type I with the oval flange, so order by the designation your drawing quotes. |
|---|---|
| Indoor post insulator | This part passes through a wall and seals the penetration. A post insulator only supports a conductor inside one enclosure. |
Use guide
Before You Order And After It Arrives
- Confirm the wall opening matches the flange before ordering
- Seal the penetration at the flange face on installation
- Keep external conductor loads within the 7.5 kN bending figure
- Check the leakage surface is clean before each energisation
