Porcelain Insulators For Overhead Line Contractors
Replacement insulators whose groove width or spindle bore does not match
What Gets In The Way
- Replacement insulators whose groove width or spindle bore does not match
- Conductors slipping during stringing before the permanent tie is made
- Insulator weight that slows pole work on a long build
- Mixed designations across a project that make procurement slow
What This Sector Needs From A Supplier
- Dimensional figures published against the series drawing
- Stringing sleeves where crews pull line by hand
- Light units where pole work is the constraint
- One supplier across ANSI, ShF, St, N, ZS, ALP and AS patterns

Product Families To Start From
Pin Type Insulators
Pin and pin post insulators carrying overhead line conductors on spindles, in ANSI, ShF, St, N, ZS, ALP and AS patterns.
Glass Suspension Insulators
Toughened glass disc insulators for transmission line suspension and tension strings, from 40kN to 160kN.
Post Insulators
Solid core post insulators supporting live parts in switchgear and on line supports, in GOST and threaded patterns.
Where These Parts End Up
- New distribution line construction at 10kV to 36kV
- Transmission suspension and tension string assembly
- Storm repair where the exact designation must be matched
- Line upgrades raising insulation class on existing poles
