Double-column disconnector for voltage 150 kV RDZ-150

Disconnectors of the RDZ-150 series are designed for switching on and off de-energized sections of a high voltage electrical network, as well as to ground disconnected sections of the network using built-in grounding knives.
The disconnector pole is made in the form of a two-column device with the main knives turning in a horizontal plane and consists of a base, insulating columns, a current-carrying system and a grounding device.
The contact blades of the 1000 A disconnector are made of two parallel copper bars installed “on edge”, one end of which is connected to the contact terminal by flexible connections, and a detachable contact is formed on the other. The contact blades of the 2000 A disconnectors consist of two 1000 A contact blades.
The grounding device of the disconnector includes grounding conductors permanently installed on the base of the disconnector and a fixed contact installed on the main contact blade. The main parts of the disconnector, made of ferrous metals, have a durable anti-corrosion coating - hot-dip galvanizing.
The pole to which the drive is connected is the leading pole. The drives are designed to operate disconnectors. The rotation of the drive shafts of the main circuit and the grounding circuit is carried out manually, using PR-6: PR-180 drives, or PD-14 motor drive.
Disconnectors are manufactured in the UHL climatic version, placement category 1 according to GOST 15150 and GOST 15543.
The electrical insulation strength meets the requirements for disconnectors of 150 kV voltage class according to GOST 1516.3-96. The creepage distance of the external insulation of serial disconnectors with porcelain insulators is:
- with insulation for pollution degree I – at least 270 cm;
- with insulation for pollution degree II – at least 340 (390) cm;
- for polymer insulation – at least 340 (390) cm.

We offer you documentation for the manufacture of disconnectors RDZ-150:

- Preliminary technical documentation for participation in tenders for the manufacture of disconnectors RDZ-150. We will prepare for you the necessary information to assess the possibility of manufacturing products in accordance with the requirements of tender documentation and questionnaires.
- Working drawings, 3-D models, and other necessary documentation for the manufacture of disconnectors RDZ-150 at your enterprise. If you do not plan to independently manufacture components and parts of the product, we will help you place their production at third-party enterprises. General assembly of the product and installation will be carried out at your enterprise.
- All documentation, if necessary, is adjusted in accordance with the requirements of the project, as well as in accordance with the technological capabilities of your enterprise.
- If equipment from another manufacturer is installed at the substation, we will prepare for you documentation for the manufacture of similar equipment in addition to the installed one

Advantages of working with us:

- You do not need to employ highly qualified engineers - You receive a set of documentation for the product being manufactured, which can be operated by a semi-skilled engineer.
- You do not need to manufacture prototypes of products - our experience allows us to successfully launch serial batches of products for production.
- Working according to our documentation - your specialists will receive advice on all the nuances of manufacturing RDZ-150.
