Other Product Sets
Pulley (Conductor Pulling Pulleys)
Lightweight yet durable reels for conductor and OPGW pulling. Fast, safe installation with polymer-lined grooves, closed-type bearings, and swivel heads.
Reels are one of the most critical tools that determine site speed. The aluminum alloy body, polymer-coated groove, and closed-type bearing structure reduce friction, do not damage the conductor, and efficiently transfer the pulling force. The swivel hook minimizes bending and torsion along the line; optional braking and locking mechanisms increase safety on slopes and long spans.
Key Features
- Single/double/multi-groove options, conductor–OPGW compatibility
- Closed-type bearing for low maintenance, long life
- Polymer-lined groove: gentle contact with conductor surface
- Integrated hook/rotating head, optional brake and lock
- Load tests and traceability according to IEC/EN requirements
Data Required for Selection
Conductor type and outer diameter, pulling force, span length, installation method (ground/helicopter), quantity.
Spacer (Bundle Conductor Separator – Line Spacer)
The bundle maintains a fixed spacing in conductors, reducing lower gap vibrations and collisions. UV-resistant elastomer and aerodynamic body.
Electrical and mechanical performance in bundle conductors is ensured by precise spacing and vibration control. Our spacers are adapted to projects in the 154–500 kV range with UV-resistant elastomer spacers, contoured surfaces that reduce corona risk, and bundle geometry options. They reduce labor time with quick positioning and standardized connection elements during field installation.
Highlights
- Design suitable for 2-4 bundle configurations
- Shock absorption, UV and ozone resistance with elastomer insert
- Stepped corner radii for corona control
- Clamp types: compression/tightening compatibility
- Optimization for frequency-sub-aperture vibrations
Data Required for Selection
Bundle count and spacing, conductor diameter, wind zone, clearance data, corona criteria.
Grounding Equipment (Temporary and Permanent)
Portable grounding kits and permanent grounding equipment for field safety. High conductivity, secure clamping, quick installation.
Safety during maintenance, repair, and initial commissioning processes begins with proper grounding. Our portable grounding kits feature high-conductivity cross-section cables, spark-proof clamps, and safety locks to speed up work on site. Permanent solutions, on the other hand, feature grounding rods, connection clamps, and copper strip/braid elements to create a low-impedance, long-lasting structure.
Highlights
- Color-coded phase–neutral–ground arrangement in portable kits
- High clamping torque and secure contact surface on clamps
- Corrosion-resistant connection elements in permanent systems
- Labeling/traceability for measurement and test points
- Design approach compliant with relevant safety standards
Data Required for Selection
Line voltage, short-circuit current/cross-section, connection points, site conditions, mobile/permanent requirements.
Stockbridge Dampers (AEOLIAN Vibration Dampers)
Wind-induced aeolian vibrations are damped, reducing conductor fatigue. Adjustable weights, armored wire option, and easy installation.
Under prolonged wind effects, small-amplitude, high-frequency vibrations occur in conductors and can lead to fatigue damage over time. Our Stockbridge dampers dampen vibration by targeting the frequency band with an adjustable weight design, stainless steel carrier wire, and surface-friendly clamp geometry. The armored wire option improves clamp-conductor contact and compensates for installation errors.
Highlights
- Effective damping across a wide frequency range
- Corrosion-resistant materials and surface treatments
- Clamp slip and clamping torque control
- Quick field installation; marking and positioning templates
- Compatibility with bundle conductors and single conductors
Data Required for Selection
Conductor type/diameter, line voltage, span data, wind–ice loads, damper quantity/positioning strategy.
