Construction and characteristics

Łączniki z ograniczoną zdolnością łączeniową 25A w wersji ramowej i modułowej

Connectors are three-pole appliances with one drive. Each pole is equipped with two supporting insulators – fixed or movable. Connectors can be equipped with porcelain, composite insulators with cycloaliphatic resin or silicone in an HTV rubber cover. Handles with main contacts are installed to the insulators. The main contacts are made from tinning coated, profiled copper flat bars. The construction of the contacts allows their self-guidance, and provides a large contact surface and clamping force.

Appliances, as standard, are equipped with current terminals, which allow the installation of isolated or naked aluminum electricity cables with a cross-section of 16-95 mm2 (a special design allows connecting cables with a cross-section of 120 mm2). This information must be provided while placing an order or request. Additionally, appliances with earthing switches are equipped with a flexible contact, which takes over the effects of bending on a movable appliance pole.

Connectors in the modular structure can be expanded with additional elements such as: lightning arresters, additional support insulators. They can be installed in the horizontal or vertical position.

Characteristics

  • Visible safe isolation gap,
  • fault-free operations in extreme weather conditions,
  • low wear and ageing reduction of all active components achieved thanks to the application of the highest quality switching units, which have excellent mechanical and electrical properties according to the latest norms PN-EN.

The Connector structure refers to well-known power industry solutions, which have been in use for many years now. A modified contact system allows the transmission and switching capability to be increased. The application of silicone drive insulators eliminates the risk of damage to this element. The main shaft interlock prevents faulty switching operations and considerably improves the handling safety of the appliance. Connectors can be equipped with porcelain, composite insulators with cycloaliphatic resin or silicone in an HTV rubber cover. Contact elements applied from our production units guarantees the proper electrical and mechanical operation of the appliance. Appliances are designed to power lines with considerable cable cross-sections up to 240 mm2, overhead switchgear busbar bridges and stations 110 kV/15 – 24 – 36 kV and for cable trays. Standard hand drives manufactured by ZPUE S.A. are used to control the connectors.
