Guidelines for Microprocessor-based Relay Protection Technology

The development of the relay protection based on open architecture is a relevant direction of electrical and electronic engineering. The paper presents the problem of the modern microprocessor-based relay prote. [pdf]

Does the pigtail use a heat-fusion technology

Fusion splicing uses a precision arc discharge between two electrode rods to heat and fuse the cleaved fiber ends together. Heat fusion (sometimes called heat welding, butt welding or simply fusion) is a welding process used to join two different pieces of a thermoplastic. The two pieces then cool together and form a permanent bond. Unlike a patch cord—which has connectors on both ends—the bare fiber end of a pigtail is designed to be permanently spliced (either by fusion or. Traditional Fusion Splice-On Connectors with pigtails provide factory-polished performance with field-termination convenience within harsh environments. Mass Fusion Pigtails come with all 12 fibers terminated and a ribbonized. The pipe fusion process associated with McElroy fusion machines is a widely accepted process that joins two pieces of thermoplastic pipe together with heat and pressure. [pdf]
