Synthetic Arc Quenching liner Moisture-proof arc quenching fuse tube

moisture-proof-fuse-tube-or-a-horn-fiber-fuse-tube

Synthetic Arc Quenching liner Moisture-proof Arc-Extinguishing BoneFiber Liner from Replaces conventional C-fuse tubes lined with bone fibers. The core of this “arc quench fuse tube” is a proprietary formula consisting of polyester fiber, epoxy resin, and aramid fiber.

Aramid fiber full name “aromatic polyamide fiber”, English for Aramid fiber, is a new high-tech synthetic fiber, with ultra-high-strength, high modulus and high-temperature resistance, acid resistance and alkali resistance, lightweight and other excellent performance, its strength is 5 to 6 times the steel wire, modulus for steel wire or glass fiber 2 to 3 times, toughness is 2 times the steel wire, and the weight is only about 1/5 of the steel wire. Under the temperature of 560 degrees, it does not decompose and does not melt. It has good insulation and anti-aging properties, with a long life cycle, aramid fiber can effectively prevent fabric burst, to avoid lightning arc, arc, static electricity, flames, and other hazards.
Usually, The presence of an arc caused by the melting of the fusing link erodes the core of the expulsion fuse. Carbon fragments react with water to form gases such as carbon monoxide and hydrogen in the interrupting material. These gases increase the pressure in the fuse tube and expel the debris from the fuse tube. With each removal of the interrupting debris, the dielectric strength within the fuse tube is re-established, but weakened, allowing it to interrupt the arc the next time. This repetitive arc extinguishing erodes and shortens the life of the bone fibers.

Synthetic Arc Quenching liner Moisture-proof arc quenching fuse tube Aramid fiber filler is used as the water source for synthetic arc quenching cores. The amount of filler is controlled to provide just the right amount of water to effectively interrupt and extinguish the arc. The epoxy matrix used in the s is highly resistant to moisture absorption. The water content is such that the interrupting capability of the system is not affected by ambient humidity.

Synthetic Arc Quenching liner Moisture-proof arc quenching fuse tube During the interruption of the arc, polymer fragments are eroded out of the core and these fragments enter the plasma of the arc and react with water to convert to arc extinguishing gas. The amount of core erosion is just enough to interrupt the arc. Any erosion beyond this amount is wasteful and creates unwanted gas, resulting in increased expulsion.Suitable for extreme harsh environments. Such as: humid and rainy, chemically corrosive environments, extremely cold and hot areas is select best fuse cutouts /dropouts fuse tube from Synthetic Arc Quenching liner Moisture-proof arc quenching fuse tube .
