This specification covers construction requirements for a 2-conductor control cable design consisting of tin coated copper conductors, insulated with PVC and having a high density polyethylene direct burial jacket. Conductors are listed as Type UF by UL or ETL or CSA.
NO. of Conductors
INS. Wall (Mills)
Jacket Wall (Mills)
Soft annealed tin coated solid copper conforming to ASTM B-33.
Polyvinyl Chloride conforming to UL Standard 493 for TYPE UF/TWU rated 75°C.
Insulated conductors are laid parallel.
Pressure Extruded High Density PE conforming to ICEA S-61-402, and NEMA WC5 Jacket Thickness 3/64" minimum jacket material to completely fill interstices between the two insulated conductors.
"PAIGE ELECTRIC P7072D SIZE 2C VOLTAGE1 DIRECT BURIAL SUNLIGHT RESISTANT FOR MAXI/2-WIRE SYSTEMS" RoHS. Maxi is a trademarks of Rain Bird Corporation.
Wire splices are the weak link of any electrical circuit. It is especially important to make proper joints in irrigation systems because the joints are exposed to wet and damp environments that can cause corrosion of the copper conductor, and premature failure. Paige Electric recommends the strict use of Model DBR/Y-6, as manufactured by the 3M Company (Paige specification P7364D)
The inner conductors are rated and labeled as 600V. The 48V rating on the print legend of the outer jacket is intentional, so as to prevent the use of this "irrigation cable" as "building wire." The normal uses for this cable are for Rain Bird Maxi and 2-wire systems, for which the applied/operating voltage is well below the 48V rating.
