Low voltage feeder pillars for public distribution networks

TIPI low voltage feeder pillars are installed bottom of the transformers in MV/LV public distribution substations.
At the level of the LV network's incomers, they assure general on-load breaking or making and the distribution on 4 to 8 feeders protected by fuse disconnect switches.
Additional functions provide new advantages for:
• Better awareness of the requirements for power supply continuity and the safety of property and persons.
• Preparing the 'increased intelligence' of substations; a measurement unit can be installed directly on the panel, for example for monitoring transformer data.


Improved safety

• The IP2X total insulation of the pillar protects operators who may be in proximity to the pillar or performing maintenance procedures.
• The top short-circuiting device assures the short-circuiting and earthing of the transformer LV input.
• The top and bottom voltage sockets enable operators to carry out EST (electrical safety testing) procedures quickly and safely.
• Temperature rises are limited to 65°C as specified by EDF; these are stricter values than those stipulated in the IEC standard (70°C).

Simple optimised operation

• A quick-connection interface allows the safe connection of an external emergency or maintenance power source.
• Feeders are fitted with terminals with self-snapping fuse screws to ensure the tightening torque.
• A provisional feeder is provided for temporary installations such as building sites, fun fairs, etc.
• The power supply for internal circuits and lighting is provided directly by the pillar.

Design & robustness

With its sleek design and smooth front, the appearance of the TIPI feeder pillar improves safety with large thermoset insulating fittings. Thanks to its rigidity, this excellent insulation material provides much greater robustness.

Manufacturer warranty

The pillar fully complies with HN 63-S-61 specifications, 2nd edition, and is ERDF approved. Our quality assurance procedures ensure reliability: individual tests for each pillar, traceability, comprehensive sampling tests, etc.
