IPU-10/630-7.5 I UKhL1 Wall Bushing With Oval Flange

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.

GOST

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

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 Suits

Switchgear and package substation manufacturers building to GOST
Utilities maintaining enclosed 10 kV distribution assemblies
Contractors fitting out substation buildings in CIS markets

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

How It Is Built

Rated 10 kV alternating voltage at frequencies up to 100 Hz
630 A rated current
7.5 kN minimum mechanical bending failure load
Construction type I with oval flange
UKhL1 climatic execution to GOST 15150-69
Suitable for atmosphere types I and II

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.

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
