4.Strong breaking capacity.

   Load drop-out fuse cutout is of outdoor used high voltage protective device. It can serve as an outdoor load switch as well as a fuse cutout  for distribution system.

  To be connected with incoming feeder of distribution transformer of distribution lines it mainly protect transformer or lines from short circuit and overload, and on/off loading current. Load drop-out fuse cutout is composed of insulator supporter,base plate and fuse tube; static contacts is fixed on two sides of insulator and moving contact is installed on two ends of fuse tube.

Standard

The LBUII type drop-out fuse cutout conforms with the standard as follows:

IEC

GB  15166.3

DL/T 640

The load fuse cutout structure

1. Fuse tube: is made of high intensity epoxy glass fiber pipe.

2. Base plate: is composed of embedded mechanical structure and insulator; the metal bar of the installation mechanical structure, which adheres to the insulator through special adhesive material, can bear power generated from breaking short circuit current.

 Application scope

The load drop-out fuse cutout can be applicated in the following fields:

1). Capacitor bank: LBU II load fuse cutout provides over-current protection and obvious visibleisolating distance to capacitor bank; it also supply simple and cheap breaking capacity for capacitance and current;

2). Transformer switch on/off operation: LBU II load fuse cutout can be used to switch on/off the exciting current of single-phase and three-phase transformer unit;

3). Section: LBU II load fuse cutout provides a simple and convenient segment approach to single-phase, three-phase, ring circuit and branch in a state of maintenance or unexpected conditions.

 Advantages

1). The fuse tube has advantages of nonhygroscopic, non-deforming property, large circuit-breaking capacity, resisting ultraviolet, long service life, excellent electric property, strong  insulated strength, good mechanical rigid and self-clean performance;

2). The whole  structure has advantages of good neutral performance ,easy installation, safety and reliability.
