IPU-10/630-7.5 I UKhL1 Wall Bushing With Oval Flange
Post Insulators
Product Overview
A GOST through-wall bushing that carries and insulates the live parts of enclosed switchgear at 10 kV alternating voltage up to 100 Hz. It connects indoor assemblies to outdoor switchyards or overhead lines and is also used on enclosed busbar runs. The designation spells out the build: I for insulator, P for through-type, U for reinforced construction, 10 kV rated voltage, 630 A rated current, 7.5 kN minimum bending failure load, construction type I with the oval flange, UKhL1 climatic execution to GOST 15150-69.

Key benefits
Why Buyers Choose This Part
- Reinforced construction rated for 7.5 kN minimum bending load
- 630 A rated current at 10 kV through a wall or enclosure
- Oval flange construction type I matches existing GOST wall openings
- UKhL1 execution for atmosphere types I and II to GOST 15150-69
Application scenarios
Where It Is Used
- Taking 10 kV busbars from an indoor switchroom to an outdoor switchyard
- Enclosed busbar runs passing through a fire or weather barrier
- Package substations connecting to overhead distribution lines
- Switchgear refurbishment where the wall opening must not change
Who it is for
Who It Suits
- Switchgear and package substation manufacturers building to GOST
- Utilities maintaining enclosed 10 kV distribution assemblies
- Contractors fitting out substation buildings in CIS markets
Problems it solves
What Goes Wrong Without The Right Part
- Wall penetrations that leak weather into the switchroom
- Bushings that fail in bending when the external connection is pulled
- Matching an oval flange opening that a round-flange bushing will not fit
- Climatic classification clauses that a general purpose bushing cannot satisfy

Comparison
How It Compares
| Post insulator | A post insulator supports a conductor within one enclosure. This bushing carries the conductor through a wall and seals the penetration at the same time. |
|---|---|
| Round flange wall bushing | The oval flange of construction type I matches a specific GOST wall opening, so an existing penetration does not have to be recut. |
Use guide
Before You Order And After It Arrives
- Confirm the flange is oval type I before ordering, a round flange will not fit the opening
- Seal the wall penetration at the flange face during installation
- Do not exceed 7.5 kN bending load from the external connection
- Support the outdoor conductor separately so it does not hang on the bushing
