1.Cais (Ceblau Offeryn Gwrth-fflam):
Mae ceblau BS 5308 wedi'u cynllunio i gludo signalau cyfathrebu a rheoli mewn amrywiaeth o fathau o osodiadau gan gynnwys y rhai a geir yn y diwydiant petrocemegol. Gall y signalau fod o fath analog, data neu lais ac o amrywiaeth o drosglwyddyddion megis pwysau, agosrwydd a meicroffon. Mae ceblau Math 3 Rhan 1 yn cael eu dylunio'n gyffredinol lle mae angen mwy o amddiffyniad mecanyddol a chemegol neu eu claddu'n uniongyrchol ar ddyfnder addas. Mae parau wedi'u sgrinio ar y cyd ac yn unigol ar gael o fewn yr ystod. Ar gyfer gosodiadau lle mae tân, allyriadau mwg a mygdarthau gwenwynig yn creu risg bosibl i fywyd ac offer.
