Product Description

XRNT4-15.5, XRNT4-24, XRNT4-40.5 High voltage fuses for oil immersed transformer backup protection
The series high voltage current limiting fuses of XRNT4-15.5, XRNT4-24, XRNT4-40.5 for oil immersed transformer protection, they are suitable for rated AC power of 50Hz, rated voltage of 15.5kV, 24kV, 40.5kV power system.
As a power transformer and other power equipment short circuit fault protection element. The fuse is installed in the transformer oil of the American transformer , which can be used in the same box with load switch of transformer .
The high voltage current limiting fuse can be connected in series with the high voltage transformer overload protection fuse to form the high voltage current limiting fuse of full range protection. The high voltage fuse will break the circuit , when the overload current exceeds the specified value for a little time. The high voltage backup fuse will break the short circuit current , when the wrong current passes through the fuse .The product can be widely used in equipment distribution protection of wind power generation, solar power generation, tidal power generation and so on .
This product has the characteristics of not causing any pollution to transformer oil when breaking short circuit current, stable time-current characteristic curve, significant current limiting characteristics of backup fuse, strong breaking ability, the maximum breaking current can reach 50kA.
We customize kinds of medium voltage and high voltage fuses according to customer 's requirements .Cooper series model number of backup fuse :
