What connectors and fittings are used in a high-voltage substation?
In a 115 to 400 KV substation, Partalum connectors and fittings join the rigid bus, the equipment and the conductor: compression terminal lugs with NEMA plate, aluminum IPS tube fittings to build the bus, insulator-base support, and connectors for autotransformer bushings. Suspension, tension and dead-end assemblies complete the connection inside the yard.
- Connection of tubular aluminum IPS rigid bus (coupling, elbow, reducer, cap).
- Conductor-to-equipment connection (breakers, disconnect switches, transformers) with NEMA 2N–8N terminal lugs.
- Bus or conductor support on base insulator, at 3" and 5" heights.
- Connection to autotransformer bushings with plain or threaded stud terminals.

What fittings are used in a 69 to 400 KV transmission line?
On 69 to 400 KV transmission lines, Partalum assemblies form the suspension and tension strings that hold the conductor at each structure, for bundles of 1 to 4 conductors per phase. String fittings —clevises, shackles, links, yokes, suspension clamps and compression dead-end clamps— transfer the conductor mechanical load to the tower, at ANSI insulator class 52.5 or 52.8.
- Vertical or "V" suspension strings for bundles of 1 to 4 conductors per phase.
- Tension and compression dead-end strings at deflection and terminal structures.
- Hot-dip galvanized forged-steel string fittings, 80–480 KN.
- Stockbridge dampers and yokes for bundle conductors.
- 69–400 KV
- ANSI class 52.5 or 52.8
- 1–4 C/F

What connectors are used in medium-voltage distribution networks?
In distribution networks of up to 35 KV, Partalum connectors resolve the joints and taps of the network in aluminum, bronze and copper: line clamps, tap connectors and compression splice joints. All parts are referenced to the CFE distribution catalog.
- Line clamps for conductor support on pole and structure.
- Tap connectors to run branches without cutting the main line.
- Compression splice joints for conductor continuity.
- Aluminum, bronze and copper depending on the conductor and the CFE reference.

What fittings support the shield wire on a transmission line?
The shield wire (overhead ground wire) protects the transmission line against lightning strikes and is held by its own set of Partalum fittings: suspension and dead-end assemblies for shield wire, plus equipotential rings that control the potential gradient across the string. They are used in the same 69 to 400 KV range as the line they protect.
- Shield-wire suspension assemblies at the top of the structure.
- Shield-wire dead-end assemblies at tension and terminal structures.
- Equipotential rings for gradient control across the string.
- Clamps and splices specific to shield wire (AS / OPGW to be confirmed).
