2 OPIS Potporni izolatori tipskih oznaka CPI 20, CPI 30, SAeb i SBeb namijenjeni su za unutarnju montažu u niskonaponskim elektriènim postrojenjima, distribuciji, industriji i brodogradnji. Tijelo izolatora izraðeno je od visokokvalitetnog duroplasta - poliester pojaèan sa staklom tako da se izolatori mogu koristiti i u tropskim uvjetima. Materijal tijela izolatora ima otpornost na puzajuæe struje CTI > 600 prema normi IEC 60112 i stupanj samogasivosti V0 prema normi UL94. Prikljuèni dijelovi su pocinèane èeliène matice koje omoguæavaju jednostavnu ugradnju izolatora. Izolatori se mogu koristiti kod temperatura okoline od - 40° C do 130° C. Elektriène karkteristike su u skladu sa normama IEC 62231, IEC 60168 i IEC 60660. DESCRIPTION The spacing insulators with type designation CPI 20, CPI 30, SAeb and SBeb are intended for indoor installation in electrical equipment, distribution, industry and ship - building. The insulator body is made of high - quality thermo - setting plastic material - polyester reinforced with fiberglass. This material is tropic and termite resistant. Material of the insulator body has leakage current resistance - CTI > 600 to standard IEC 60112 and level flammability V0 to standard UL 94. The connection parts are zinc - plated steel female - threads which enables easy mounting. The insulators are available in ambient air temperature - 40° C to 130° C. Electrical characteristics are in accordance with standards IEC 62231, IEC60168 and IEC 60660.
