ShF-20G1S High Voltage Porcelain Pin Insulator
Pin Type Insulators
Product Overview
The ShF-20G1S variant of the 20 kV porcelain pin insulator family, listed separately from the base ShF-20G1 because of its coupling arrangement. It carries distribution conductors on pin spindles at 20 kV and is ordered against the 20G1S suffix where the drawing calls for that specific coupling. Detailed test figures for this variant are confirmed against the drawing on request.
Key benefits
Why Buyers Choose This Part
- Ordered directly against the ShF-20G1S designation
- Part of a full ShF range so a project ships from one factory
- Glazed porcelain body built for long outdoor exposure
- Pin mounting works with the spindles already on the poles
Application scenarios
Where It Is Used
- 20 kV distribution lines using the 20G1S coupling variant
- Networks where the drawing specifies 20G1S and not the base 20G1
- Storm repair where the exact designation must be matched
- Line projects consolidating ShF family purchasing
Who it is for
Who It Suits
- Overhead line contractors at 20 kV
- Utilities maintaining ShF-insulated networks
- Distributors serving CIS and Northern European specifications
Problems it solves
What Goes Wrong Without The Right Part
- Drawings that name 20G1S and will not accept the base variant
- Coupling arrangements that a general pin insulator does not provide
- Slow supply of variant designations from local stock
- Split orders across several suppliers for one insulator family
Technical features
How It Is Built
- ShF-20G1S designation
- 20 kV distribution class
- Glazed electrical porcelain body
- Pin spindle mounting with the 20G1S coupling arrangement

Comparison
How It Compares
| ShF-20G1 with stringing sleeve | Same 20 kV family. The 20G1S is distinguished by its coupling arrangement, which is why it is held as a separate designation. |
|---|---|
| ShF-20G | The 20G is listed with two coupling modifications of its own, one with a polyethylene capsule and one with a composite thread to the Finnish SFS standard. |
