Description

Support composite insulators with non-conducting upper fitting (PKI PA)on base of conclusions of professional researches we developed support composite insulator with upper fitting from insulating material which is resistant against atmospheric impacts and UV radiation.We produce support (pin) composite insulators type PKI with upper fitting from insulating material PA with normal (N) and larger (L) creeping distance and with already mounted spring clamp (S).They are suitable for all types of environments with temperatures from **0°C to **0°C, because of self-cleaning also for more aggressive environments (industry, coast, desert climate). .Support (pin) composite insulators with upper fitting from insulating material were tested at electric institute and they suit to demands of standards IEC ****2, IEC ******1, IEC ******1, IEC ******1 and IEC ****5. We produce strain composite insulators (NKI) with two creeping distances (N and L) and with all possible fittings, which are eye (U), ball (B), socket (P) and clevis (V), as also version for drive (I). All technical and remaining information about strain composite insulators and fittings are stated in our catalogue on the web side. ZnO middle voltage surge arresters 2SS*5N are designed for protection of middle voltage power networks against all kinds of excess voltage. They are produced and tested according to standard IEC ******4. The base for middle voltage surge arresters are zinc oxide (ZnO) varistors, which are very precisely made elements. All elements of surge arresters are mechanically combined to whole with three mechanically and electrically highly resistant epoxy strips. This assures a large load of surge arresters, also with flexible and torsion force. Silicone rubber that we use for housing was developed especially for such types of surge arresters. ZnO low voltage surge arresters that we produce are designed for indoor and outdoor xxxxx ISDE http://xxxxx/index.php?jezik=2
