terminal connectors
About The Product
erminal Connectors are critical components used to connect conductors to electrical equipment such as transformers, circuit breakers, disconnect switches, and busbars. These connectors provide a secure mechanical and electrical interface, ensuring efficient current flow and long-term reliability in both overhead and substation installations.
featueres
1. High Conductivity: Made from high-quality aluminum or copper to reduce electrical resistance.
2. Mechanical Strength: Designed to withstand electromechanical stresses from fault currents and wind loading.
3. Corrosion Resistance: Usually tinned (for copper) or provided with anti-oxidation grease (for aluminum).
4. Temperature Resistance: Operates reliably at high temperatures (up to 90°C–105°C under normal, 250°C under fault conditions).
5. Customizable Ends: Available with flat palm, eye bolt, or stud-type ends to match equipment terminals.
6. Anti-Galvanic Designs: Bi-metallic options prevent dissimilar metal corrosion in Al–Cu transitions.
usage
1. Terminate power conductors at equipment terminals.
2. Facilitate flexible connection between the conductor and electrical apparatus.
3. Allow efficient and safe current transfer without overheating or corrosion.
4. Enable easy installation or replacement during maintenance.

INSTALLATION
➥ Prepare the Conductor:
Strip insulation, clean contact area, apply joint compound if required.
➥ Fit the Connector:
Slide or place the connector as per type.
➥Crimp or Bolt:
For compression types, crimp using appropriate dies.
For bolted types, tighten to torque values specified by the manufacturer.
Inspection:
Check for secure fit, correct alignment, and no visible damage.
➥Protection:
Apply insulating tape or heat-shrink as needed.
