Power Distribution Porcelain Drop Out Fuse Cutout With KEMA Certified

Our drop out fuses can be used in outdoor medium and high voltage AC systems, mainly to protect transformers and distribution lines from short circuits and overloads, and to prevent other distribution equipment in the circuit from being damaged due to excessive current.
When the current in the circuit is too high and the fuse blows, it falls onto the base.
The function of a standard fuse is similar to that of a 300 ampere overhead isolation switch. High voltage isolation switches or disconnect blades can also be used for this purpose.
The product fully complies with the latest standards of IEC60282-2, ANSI C37.41, and ANSI C37.42. The product can meet the requirements

The advantages of fuse tubes


1.The fuse tube is made of epoxy glass fiber, lined with anti ultraviolet coating and copper arc extinguishing material, which will not absorb moisture or deform. In addition, it has strong UV resistance, a thick arc extinguishing layer, and good arc extinguishing performance, with a long service life. In addition, the upper part of the fuse tube can prevent water from entering, ensuring that there is no water in the fuse tube.

2.Due to interchangeability, a night light can be attached to the fuse holder to reflect light when illuminated at night, making it easier to know the location of the fuse holder and facilitating workers to operate at night, reducing labor intensity.

3.The fuse holder adopts a single exhaust (downward) with a solid cover to avoid the threat of free gas to the circuit, unnecessary mechanical damage or short circuit. At the same time, it can greatly improve the short-circuit current and interruption performance of the fuse.



Characteristics of fuse base


We have the following two types of bases, and the characteristics of each base are as follows:

1.Ceramic insulator base: Made of bird proof ceramic, advanced casting technology, and international standard cement, it can prevent the ceramic body from cracking due to thermal expansion and contraction. Ceramics have strong durability and effectively extend their service life. The components of the product are made of high-quality copper to reduce circuit losses.

2.Silicone rubber insulator base: The silicone rubber material has passed a 1000 hour salt spray test. This material makes the product lighter in weight than ceramic materials and easier to install.
