100 Amp 100a Cut Out Fuse 20 Kv

The 20kV drop out fuse cutout is an outdoor protection device designed to protect distribution transformers and overhead lines from overloads and short circuits. It combines the functions of a disconnector and a fuse, which provides both protection and visible isolation for 20kv power systems. Under fault conditions, the fuse link melts to cause the fuse tube to drop open, which clearly indicates circuit disconnection for operator safety.

The common applications of a 100 amp 100a cut out fuse 20 kv:

1. 17.5 kV to 24 kV distribution lines;

2. Transformer protection for pole mounted substations;

3. Rural and industrial power distribution networks.

Product FAQ:

1. What is a 20 kV 100 A cutout fuse used for?

A: It is mainly applied on 17.5 kV to 24 kV overhead distribution lines and pole mounted substations. The fuse tube provides protection against overloads and short circuits while to provide a visible point of disconnection after operation.

2. What materials of a a 20 kV 100 A cutout fuse are used for the insulator?

A: Two options are available:

(1) Porcelain: high mechanical strength, good resistance to pollution;

(2) Silicone rubber: lightweight, excellent hydrophobic and UV-resistant properties.

Both types ensure reliable insulation in outdoor conditions.

3. Can the fuse tube be reused after operation?

A: No. Once the fuse link has suffered the overload or short circuit, and the tube has dropped open, the fuse link must be replaced. Fortunately, the fuse tube and hardware can usually be reused if it is not damaged and clean, but the fuse link itself must be replaced.
