Product Details

The fuses mention in the table below will be exposed to the following environmental conditions:
   Maximum altitude above mean sea level less than 1,000 m;
   Maximum ambient air temperature 400C;
   Maximum daily average ambient air temperature 300C;
   Minimum ambient temperature150C; and
   Maximum relative humidity 100%.

The fuse-links and fuse-end fittings shall be of the following ratings (table below) and comply with the IEEE Std C37.4 -2016 or an equivalent international standard. The fuse- links shall be used primarily for protection of distribution transformers, laterals and sub- laterals.
The fuse links shall be capable of withstanding 125% ofthe transformer rated full load current continuously and periodic over-loads up to 150% ofthe transformer rated full load current.

The current-time characteristics of the fuse-links offered shall be submitted with the tender
Markings shall be provided on the fuse-links in accordance with ANSI/IEEE Standards.
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 PRW OEI DTF 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 DI
CONNECT 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.
