TYPE "OEI" "PRW" STANDARD CUTOUT DISTRIBUTION TECHNICAL SPECIFICATION
The Fuse Cutout type DHE was developed to operate in overhead distribution systems rated at 12-15 kV and 15-27,kV or 27-38 kV grounded systems with 100 or 200 A nominal currents.
Especially designed to protect transformers, capacitors, cables or lines.
It is robust construction, made of rigorously tested material, will interrupt all faults under the
most severe conditions, maintaining mechanical and electric characteristics.
The inserts, hardware and structural bolts and nuts are made from heavy galvanized steel.
The Fuse Cutout type OEI PRW can be applied on all three-phase system rated at or below the maximum operational rating of the cutout. In highly polluted environments or environments with high levels of salinity, a cutout may be used with a higher nominal rating than
that of the system where it is being installed, where the insulator will have a greater leakage distance to ground, allowing for
increased safety against discharge. For an even better protection against abrasions, the hardware may be supplied in stainless
steel. The fuse cutout type OEI PRW has attachment hooks in aluminum.
The Fuseholder has a stainless steel flipper, which associated with a spring doesn't allow the fuse link to be subject to traction
forces of over 3 Kgf, especially during closing. This me chanism also allows for high speed fuse link separation. The fuse cutout
type OEI PRW allows for the insertion of the fuse tube in a precise man ner and always in perfect alignment, due to the large distance
between the grunion pocket. Lower contact, silver-to-silver, provide du el current path, independent of hinge pivot. Stainless-steel
back-up springs prevent arcing when tube rises in hinge during recoil. The fuse cutout type OEI PRW may be transformed into a DICONNECT up to 300 A, by simply changing the fuse tube for an electrolytic copper blade.
The DHE Fuse Cutouts conform to ANSI and IEC standards, with independent tests performed At:
CPRI Always use quality fuse links. Only they can assure excellent performance.
