Apparatus For Overhead Lines/Cables TRIZ Cases

A rib-and-notch rotating latch lets an isolating link close securely from above ground without lifting, improving overhead operation and safety.

Inductive power coupling lets a cable repair robot work on energized medium- and high-voltage lines, reducing manual risk and outage time.

A captive hinge between roller axes lets one pulley block fold onto multiple conductors, cutting on-site assembly time and improving installation safety.

A spring-loaded self-latching garland roller simplifies conductor replacement, reducing manual fastener handling and drop risk on overhead lines.

Auxiliary supports and transfer buses let DC two-phase conductors be replaced live while preserving phase position and stable power delivery.

Clamps and peg-engaged lifting plates suspend a utility pole cross-arm so linemen can replace it without removing energized lines.

A pivoting wheel and guide-arm support keeps electrical power conductors from sliding while staying lighter and easier to mount on utility trucks.

A motorized carriage running on a supported pathway deploys cabling through trays faster while reducing labor, injury risk, and cable damage.

A rotation actuator and insulating truss keep wire holders vertical while lifting sub-conductor bundles with safe clearance from energized lines.

A jaw clamp with a strap slot and pivoting gate secures a distribution line to a hoist, controlling the free end during tensioning.

An elastic C-channel clamp maintains conductor compression through thermal expansion cycles while reducing weight and installation difficulty on energized lines.

Clamps and peg-engaged lifting plates suspend a utility pole cross-arm with energized lines attached, avoiding temporary phase-holders.

A rotatable retractable hook and intersecting channels help move hot line tap clamps securely while maintaining high-voltage clearance.

A ratchet locking mechanism lets a blanket clamp stay easy to operate while resisting wind-driven movement and dislodgement.

An adjustable base and extendable guide arm improve wire loading, sheave alignment, and transport durability without disengaging the block.

A hooked cap lifted onto a utility pole tip secures cable from the ground, avoiding high-place work and enabling pole inspection.

Closed-loop speed measurement and force adjustment keep transmission lines moving uniformly through conduits, reducing damage and manual tuning.

Distributed air feeds and pressure sensing keep conduit pressure stable, advancing transmission lines without stretching, coiling, or crinkling.

Two preformed conductive packing layers restore cable conductivity and strength even when many outer strands are severed.

Oscillating sliders and limiting teeth let this cable laying roller unit adapt to varying paths while preventing excessive cable curvature and damage.

Hard, low-friction groove materials and adjustable sliders cut roller wear while protecting cables from abrasion, crushing, and torsional stress.

A central wheel, oblique guide arms, and a pivoting support arm restrain conductor movement while keeping utility truck setup lighter and easier.

A delta conductor layout and non-conductive strings shrink transmission right-of-way while lowering EM fields and preserving reliable 345 kV power flow.

A temporary winch column supports conductors and static lines during pole replacement, cutting labor, outage time, and handling risk.

Adjacent cam cleats hold installation rope above ground, preventing sagging, road closures, and worker safety risks during power line setup.

Helium balloons counteract gravity to prevent falling cables, eliminating costly road closures and night work delays.
