- IO-10/4 UKhL3 Ceramic Post Insulator For Line Supports
Product Overview
The IO-10/4 UKhL3 listing of the 10 kV GOST post insulator, held on the original catalogue as a separate item from the IOR-numbered variant. Body dimensions are 54 mm diameter by 272 mm height with a 75 kV minimum puncture voltage, strength class II and UKhL2 climatic group. It fixes conductors and cables onto overhead line supports and is made from quality electrotechnical ceramic for weather resistance.
Why Buyers Choose This Part
- Direct replacement where the drawing names IO-10/4 UKhL3 specifically
- Ceramic body that resists atmospheric attack on exposed line supports
- Simple to mount on standard support brackets
- 75 kV puncture margin on a 10 kV network
Where It Is Used
- Building 10 kV overhead line sections on existing support designs
- Maintenance replacement on lines already fitted with IO-10/4 units
- Distribution projects specified from GOST catalogues
- Stocking a common CIS post insulator for fast dispatch
Who It Suits
- Line construction crews working from GOST parts lists
- Regional utilities maintaining 10 kV overhead networks
- Traders supplying CIS electrical porcelain
What Goes Wrong Without The Right Part
- Drawings that name IO-10/4 UKhL3 and will not accept a substitute designation
- Insulators that lose insulation value after heavy weather exposure
- Conductor fixings that loosen and cause line faults
- Slow replacement supply during a fault repair window
How It Is Built
- 54 mm diameter body
- 272 mm height
- 75 kV minimum puncture voltage
- Strength class II
- UKhL2 climatic group
- Weather resistant electrotechnical ceramic

Materials
- Electrotechnical ceramic body
- Metal fixing hardware
Process
- Forming
- Glazing
- Firing
- Assembly
- Routine electrical test
Testing
- Minimum puncture voltage verified at 75 kV
- Height and diameter checked against the 272 mm by 54 mm envelope
- Surface glaze inspection
Certification
- ISO 9001 quality management system
Customisation Options
- Marking under the designation your parts list uses
- Production to drawing or sample
- Export packing to your route
How It Compares
| IOR-10/3.75 II UKhL2 listing | Same 54 mm by 272 mm envelope and the same 75 kV puncture figure, held as a separate catalogue item so buyers can order against the exact designation on their drawing. |
|---|---|
| Glass line insulator | Ceramic is the established choice on these GOST support patterns and matches the existing fittings without adapting the bracket. |
Before You Order And After It Arrives
- Order against the exact designation printed on your parts list
- Mount on a flat seat so load is spread across the base
- Check the conductor tie at each inspection round
- Replace any unit with a cracked glaze rather than cleaning it
