TZK busbars

«Russian Busbar Center» offers factory-assembled TZK air insulated busbars and various types of in-house bus ducts. The cost of our products is always stable as they are manufactured in the territory of the Russian Federation. We are using mostly domestic component parts and materials. Our products are supplied as fully ready-made. This reduces the period of installation works and cuts labour costs.

Closed TZK busbars with the overall metal casing for the rated current of 4,000 A are used for electrical connections of equipment. They are widely used in the circuits of electric power stations and converter substations with switchgear cabinets. These busbars are also intended for the circuits with turbine generators and step-up transformers. In addition, TZK busbars may be used at substations of various electric power systems, at transportation, industrial infrastructure facilities, etc.

Calculating the cost of TZK busbars

The cost depends on the following factors:

Busbar series
Route lengths
Technical parameters
Types of busbar sections
Climatic version of the busbar
Type of attachment

All this information is obtained by our specialists in the process of individual work with the customer. On the basis of all the received data, a technical and commercial offer is formed.We suggest that you fill out the questionnaire and send it to us by email:

BUSBAR CONSTRUCTION WITH AIR INSULATION

Figure - Straight section of TZKR and TZK busbars. a) TZKR series (with partitions), b) TZK series. 1-housing; 2-bus current-carrying; 3-insulator; 4-dividing partition
Busbars consist of a casing 1, common for the three phases, and current-carrying buses 2 of the corresponding profile and cross-section. The tires are fixed to the insulators 3 inside the casing at the vertices of an equilateral triangle by means of special tire holders.
The partitions are designed to exclude the possibility of transition of a single-phase short-circuit to an interfacial short-circuit.
