Product Details


Ceramic Fuse Cut Out


1.Application

The primary purpose of any Cut-out Fuse is to provide protection to the lines of your system and the various apparatus on those lines such as transformers and capacitor banks. Cutout fuse provide reliable protection from low-level overloads that just melt the fuse link, intermediate faults, and very high faults, through maximum interrupting capacity.

2.Features and detailed description

High Voltage Cut Out Fuse, 11kv Drop Out Fuse

   2.1 Mounting bracket

Cut-out Fuse comes packed one per carton including a NEMA Heavy Duty “B” bracket with captive 11/2”bolt from cross arm mounting.

Type “X” bracket, also for cross arm mounting, provides 2 5/8” additional clearance between the cross arm and the cutout.

Higher interrupting capacities

By using a copper arc shortening rod inside the top of the fuse tube, higher interrupt ratings are obtainable. An arc shortening rod is attached to the cap of some fuse tube and lowers the fuse link within the fuse tube. This permit a much shorter arc, resulting in less arc energy, and higher interrupting capacities.

For 200 A tubes, it allows for full voltage rating. It is necessary to use fuse links with removable button heads when arc shortening rods are employed.

   2.2 Quality construction
The top contact is attached to the galvanized-steel hood by a stainless rivet to provide a smooth self-aligning action during closing even in severely corrosive environments. The top contact provides a socket-type cavity for latching the fuse holder and prevents any possible over-travel of the fuse holder. The top contact is made of a highly conductive copper strip with silver-plated embossments to resist corrosion. The contacts are held under constant pressure designed to maintain firm contact with the fuse holder contact surface until fault interruption is accomplished.
   2.3Hinge
The hinge on the Cutout Fuse employs large pivot areas for the fuse holder’s trunnion and is cast of a copper alloy chosen for its strength and corrosion resistance. The hinge contacts are highly conductive copper alloy stampings and are plated to assure low resistance current transfer from the trunnion casting. The parallel current paths are backed up by high strength cantilever springs and are riveted to the hinge castings. Fuse holder can be dropped into place and easily lifted up and out. No tricky maneuvering.
   2.4 Fuse holder
The solid cap on the single vent fuse holder is a copper alloy, silver-plated to provide efficient current transfer. An integral ring is provided in the top tube casting for opening and closing the fuse holder with conventional disconnect tools from the ground, from a bucket truck or from the pole.
The toggle type trunnion casting is a selective silver-plated bronze for efficient current transfer to the lower hinge contacts. A cam shaped projection on each side of the trunnion casting provides high pressure parallel current paths to the lower contacts. These projections, or pivot pins, are cast full round for smooth rotational operation in the hinge. The link ejector assists in arc interruption during low fault current or excessive overload conditions. A groove in the center of the link ejector allows the fuse link’s pigtail to go directly from the fuse tube to the attachment nut. A curved ejector minimizes bending stresses in the pigtail to prevent broken strands. A stainless steel torsion spring on the link ejector helps to rapidly eject the link from the bore of the fuse holder during interruption. The 200 ampere link ejector has a wider groove area and increased spring force to accommodate the larger links.
   2.5 Fuse tube
The 1/2 inch inside diameter of the Cutout Fuse 100ampere fuse tube increases internal pressure giving superior and reliable expulsion action. During frequently encountered intermediate fault ranges this diameter also permits higher TRV (transient recovery voltage) values to be tolerated. This small bore design eliminates any concern related to high impedance phase-to-phase faults on ungrounded wye and delta systems.
The inside liner is constructed of a synthetic arc-quenching material. The tube is made of fiberglass which permits the smaller bore and provides a higher burst strength. It is protected from the weather and environment by a special ultra-violet resistant coating.
Also, the Xikai fuse tube operates with fuse links from all major suppliers.

5.FAQ

 1. Q: Do you have a catalogue? Can you send me the catalogue to have a check of all your products?

     A: Yes, We have product catalogue. Please contact us online or send an Email to sending the catalogue.

 2. Q: I need your price list of all your products, do you have a price list ?

    A: We do not have a price list of all of our products. Because we have so many items, and it is impossible to mark all of their price on a list. And the price are always changing because of the producing and raw material cost. If you want to check any price of our products, please feel free to contact us. We will send offer to you soon!

 3. Q: I can’t find the product on your catalogue, can you make this product for me?

    A: Our catalogue shows most of our products, but not all. So just let us know what product do you need. If we do not have it, we can also design and make a new mould to produce it. For your reference, making an ordinary mould will take about 20-30 days.
