In spanish Varilla de Protección, in English Armour Rods, with two letters meaning the raw material which they are made from. AL (Aleación de Aluminio= Aluminium Alloy), AC (Acero Galvanizado=galvanized steel), AW (Aluminium Clad Steel-ACS), CW (Copper Clad Steel-CCS), AA (Acero aluminizado=Aluminized steel), and with two series of three numbers, they show the diameter range of the specified conductor.
Example: VPAL 093-099 is an aluminium alloy armour rods for a cable with a diameter range from 9,31 to 9,90 mm.
Besides, like it has been indicated, the colour code for the fitting, is the central mark, it is given to facilite the assembly. This denomination is completed with the letter D (Derechas=right hand lay) or I (Izquierda=left hand lay) depending on the direction of lay of conductor.
VERY IMPORTANT: The lay direction of the fittings must be identical to the outer layer of the specified conductor.
Finish and Appearance he rods of the fitting are refaced in the ends to avoid damages in the assembly and to the specified conductor. Refacing of the ends is made by abrasion in the rods up to 4,62 mm. When the rods are of aluminium and the diameter is major or equal to 5,18 mm, are BALL- ENDED rods.These rods can be made with PARROT BILL ENDED rods, if the electric line requires this type of end for corona protection.
Each set of rods are tied with a ribbon of same colour of the colour code. When the rods are intended for the biggest diameters, they are tied with a plastic clamp, and identified with its colour code.
