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

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.

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

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 Suits

Switchgear manufacturers building complete distribution devices
Power station and substation maintenance engineers
Distributors supplying GOST wall bushings

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

How It Is Built

Rated voltage 10 kV
Rated current 630 A
80 kV lightning impulse test voltage
7.5 kN minimum bending failure force
300 mm path leakage length
Suitable for type I and II atmospheres to GOST 15150-69
Frequencies up to 100 Hz

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.
