Totally Insulated Framing System (TIF) 3-Phase TIF Tri-Frame – Distribution
15kV – 69kV (Patent No.: US 9,685,772)
Generally, Insulators are used to support electrical conductors on Overhead Distribution and Sub Transmission systems to prevent line to ground contact. Conductors may be attached to Deadend/Suspension Insulators and suspended from Crossarms or supported on Line Post/Pin Insulators on Crossarms or Side Post Brackets. Conventional Crossarms have service life limitations due to wood rot, steel corrosion or fiber reinforced polymer (FRP) deterioration.
K-LINE INSULATORS LIMITED’s (KLI) innovative design reduces many common concerns and difficulties encountered with wood, steel or fiberglass Crossarms.
KLI’s Totally Insulated Framing (TIF) Systems offer alternative line designs that increase service life, reduce installation labour costs, enhance system reliability and improves safety during installation. KLI TIF Systems are a new, cost effective approach for Line Design, Construction, Maintenance and “Hardening” of Distribution and Sub-Transmission Systems.
Summary of TIF Features
- TIF Tri-Frame offers improved safety in application. Rapid installation reduces Lineman exposure time in energized work environment
- Improved system reliability with integrated KLI proprietary Silicone Rubber Insulators
- Corrosion resistant Aluminum Alloy End Fittings and Frame
- TIF eliminates Crossarm life limitations due to rot, hidden corrosion and fiberglass deterioration
- TIF is lightweight and can be transported by line crews into areas difficult to access and erected in place without heavy lifting equipment
- TIF avoids vandalism associated with glass and porcelain insulators
- Improved aesthetics and compact triangular appearance
- TIF Tri-Frame Insulator configuration discourages “roosting” thus minimizing the probability of wildlife contact issues.
