保險絲耐燃性繞線導線電阻

INTRODUCTION
The resistor element is a resistive wire which
is wound in a single layer on a ceramic rod,
with tinned connecting wires of electrolytic
copper welded to the end-caps. The ends of
the resistive wire are connected to the caps by
welding. The resistors are coated with layers
of green color flame-proof lacquer. Overload
protection without risk of fire. Wide range of
overload current
