Construction
CAAI conductors consist of two or three phase conductors concentrically braided plus one or two conductors for lighting wiring around a support or support. The phase and lighting conductors are made of hard hardening aluminium alloy 1350-h19. The holder is a class A, extra high strengh (EHS) galvanized steel cable for CAAI-S type cables and 6201-t81 aluminum alloy (which serves as neutral) for CAAI type cables. The conductors and the support are isolated with reticulated polyethylene (XLPE). The phase conductors are differentiated by ribs extruded longitudinally over the insulation. Its form of packaging is spools in lengths according to customer needs.
Applications
The aluminum conductors type CAAI and CAAI-S are braided classes aa and a and are used for secondary distribution lines of electrical energy, can be installed directly buried, in pipelines or electrical pipelines. This type of conductor can be used in dry and wet places, its maximum operating temperature is 90 ° c and its operating voltage for all applications is 1 kv.
