PIWO Insulated feedthroughs

A wide range of feedthrough configurations enables precise integration with the device and its enclosure.
PIWO feedthroughs can be equipped with threaded housings and sleeves of various diameters. Additionally, depending on application requirements, copper conductors, fiber optic cables, and various types of connection sockets and terminal blocks can be used. Compliance of the design with the requirements of PN-EN 60079-0 and PN-EN 60079-1, together with the highest manufacturing quality ensuring the required level of explosion protection, has been confirmed by the EU-type examination certificate KDB13ATEX0042X. The certificate allows the use of feedthroughs in Ex equipment
without the need for assembly recertification.
PIWO for use in Ex explosion hazard zones.
The PIWO-type multi-core insulated flameproof feedthroughs are designed to route conductors between compartments within flameproof enclosures or between a flameproof section of an enclosure and a compartment with a different type of explosion protection. These feedthroughs are intended for use in electrical equipment of Group I, Category M2, and industrial equipment of Group II, Category 2 (for gas groups IIA, IIB, and IIC), operating in hazardous areas with explosive gas and/or dust atmospheres.
