The vacuum switch of 10 kV to 1000A

BB/TEL - the quality and reliability checked by time

At the end of the XX century the vacuum BB/TEL switch made revolution in the world of the switching equipment 6-10kB and allowed to make break on the way of creation modern CREWE high reliability which would not demand service of the switching device throughout all service life. Ease and unpretentiousness of a design of BB/TEL allows to build in the switch any existing cell of CREWE or KSO or to create new with unique consumer qualities.
Today BB/TEL is applied on five continents of the world, than confirms the compliance to the most strict requirements of operation, be it the Kola Peninsula with winter sea climate, or Egypt with its exhausting heat in the winter and in the summer, or Vietnam with its humid climate.
The variety of decisions on use of vacuum BB/TEL switches allows to use the device both at modernization of the existing distributing devices, and at new construction.
The vacuum BB/TEL switch contains the switching module of the ISM15 series, and also the control unit of the BU/TEL-220-05A, BU/TEL-12A or BU/TEL-21 series in the structure. The BU/TEL-220-05A control unit is used only together with the BP/TEL-220-02A power supply unit.

Variety of decisions

Variety of the existing projects of use of BB/TEL switches in modern CREWE and KSO, distributing devices of last years, cells of foreign producers, in combination with invaluable experience of experts "Taurida the Electrician", saved up for many years of work, can be effectively used for the solution of the existing problems of modernization and new construction of facilities of an electronetwork complex on modern component base.

Not maintainability

Application of BB/TEL allows to refuse costs of service of the switch as throughout all service life carrying out average and capital repairs is not required completely.

Adaptability

The possibility of application of uniform execution of the BB/TEL switch in all existing ranges and on all types of tension of expeditious food allows to use the device without damage to its technical and operational characteristics, allowing not to form at the same time the wide nomenclature the ZIP or almost completely to refuse it.
Additional terminal sockets on control units of BB/TEL switches give the chance of full repetition of the schemes RZIA constructed on electromechanical element base without change or processing of their topology that considerably reduces time of installation and operational costs.

Energy saving

BU/TEL control units allow to reduce significantly energy consumption on a chain of expeditious food as practically do not consume power from a network at inclusion and completely do not consume it at shutdown of the switch, providing at the same time steadily minimum time for switching operation, and also information transfer in the scheme RZIA. Even in lack of expeditious food control units of the TEL series keep a possibility of expeditious shutdown of the BB/TEL switch or its inclusion about use of the block of mechanical inclusion of BMV/TEL.
