Why Buyers Specify Strain and Guy Insulators
A guy wire that is metallically continuous from the pole to the anchor becomes a hazard the moment a conductor contacts it. A strain insulator breaks that path while still carrying the full guy tension.
Who It Is For
- Line construction contractors
- Utilities setting guy and anchor standards
- Distributors supplying pole line hardware
Core Advantages
- 53 kN and 91 kN tensile strength
- Interlocking body stays captive if the porcelain fractures
- 0.65 kg and 1.2 kg per unit
- Grey or brown glaze
Where It Is Used
- Guys on distribution angle and terminal poles
- Transmission dead-end structure guys
- Temporary guying during construction

Strain and Guy Insulators Questions
Where in the guy should the insulator be fitted?
Above the reach of people and livestock, and below the point a broken conductor could bridge. Your own guy standard gives the exact dimension.
Which size should we use?
ANSI 54-2 at 53 kN for distribution guys, ANSI 54-3 at 91 kN for heavy dead-end and transmission guys.
What happens if the porcelain fractures?
The interlocking body keeps the halves captive so the guy is not released immediately, but the unit must be replaced at the first opportunity.
Is the leakage distance sufficient to hold system voltage?
A strain insulator is not a continuous-duty insulator. It interrupts the metallic path and withstands transient contact; design against the published dry and wet flashover figures.
Do you supply guy grips and thimbles?
We supply the porcelain component. Tell us which guy hardware you use and we will confirm dimensional compatibility.
