La base cortacircuitos en "V" monta aisladores de columna con
armaduras metálicas externas y línea de fuga en función de los niveles
de contaminación I-III-IV asignados.
Su diseño permite el accionamiento por pértiga desde una posición mas
cómoda para la maniobra, al conseguir un ángulo de 45º con respecto a
la base de sujección.
Incorpora un tubo fusible con capacidad para eslabones de hasta 100A
, y es totalmente intercambiable con los modelos de una columna y
modelos de otros fabricantes.
El interior del tubo portafusible está constituido por un recubrimiento
vegetal lo que le confiere un poder de extinción superior a otros
modelos (según fabricante).

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.
Third: Specification of Cutout fuse:
- Scope of The Tender:
- General Requirements:
The cut out is fastened on a common cross arm which can be of steel, The contacts of the expulsion fuses are chosen in such a way as to ensure reliable contact pressure and drop out of the fuse carrier when operating.
The fuse carrier consist of an insulating tube into which the fuse link is built-in. The fuse link consist of a standard copper wire and a gauged silver wire as a fuse element. The fuse links are designed for standard rated current from 10A to 50A.
By its methods of operation the expulsion fuse cut outs is a switch-disconnector which breaks current within approximately 20msec and does not limit the current. After the fuse element is being melted the fuse carrier drops out from the upper fuse-base contact and performs reliable disconnection. The use carrier stays hanging on the bottom of the fuse-base contact. The operation of operator removes the fuse carrier by an insulating rod, insert a new fuse link and close it again. Expulsion fuse cutouts are applied as protection for distribution transformers and supply mains. especially for the protection against the undesired action of the short circuit current and earth fault current.
Technical data, dimensions, catalogues required.
The expulsion fuse cutouts should be supplied with the necessary element fuses rating 20A, 40A according to the approval of the client.
- Construction:
There for it should be supplied completely with fuse holder and fuse link elements with holder bimetal clamp connectors. The fuse link element shall be of a current limiting type in accordance of IEC 60282. The rating of both 33 and 11kV (24 kV insulators) fuses cutouts shall be 100A
