Product Description

GENERAL

((H)RWW5-40.5 series outdoor high-voltage drop fuse (hereinafter referred to as "fuse") is the most common short-circuit protection switch for distribution line branch and distribution transformer.

The fuse is suitable for short circuit and overload protection of transmission lines and power transformers in the power system with AC 50Hz and a rated voltage of 35kV. Under certain conditions, a no-load overhead line, no-load transformer, and small load current can be opened and closed.

Fuses are widely used in distribution lines and the primary side of distribution transformers as protection and equipment switching operations. It is installed on the branch of the distribution line to reduce the scope of power failure.

The fuse complies with technical standards such as GB / T 15166.3-2008 high voltage AC fuses Part 3: jet fuses, DL / T 640-1997 technical conditions for ordering outdoor AC high voltage drop out fuses and fuses.

The fuse complies with technical standards such as GB / t15166.2-2008 high voltage AC fuses Part 2: current limiting fuse.


MODEL AND MEANINGS


MAIN ADVANTAGES
