Neutral Earthing Resistors
Our resistors are generally composed of the
active part (resistor blocks) and a steel
The housing is constructed entirely of sheet
steel, mounted on a steel frame and for
outdoor installation suitable (dusty, humid
Optionally can be delivered in zinc coated
execution or in stainless steel (AISI 304).
Both the frame, the side panels and the roof
are depending on the requirements made of
2.0 or 2.5 mm thick material.
Optionally it can be supplied in protection
degree IP20, IP21, IP23, IP33, IP45 or IP54.
Resistor and the housing are constructed so that the rated current can be carried without danger for
the operator and without stress for the material.
The surface treatment is generally carried out in powder coating technology.
Standard colors are RAL 7033, 7032 and 7035. Special color build-up such as iron mica add-on or
special coloring are optional.
Resistor elements (resistor grids) itself are made of stainless steel (AISI 430 or 304).
Grounding resistor in two-room housing with
circuit breaker and current transformer.
The surface treatment is basically in powder
coating technology. Standard colors are RAL
7033, 7032 and 7035. Special color build-up
such as iron mica add-on or special colors are
available as an option.
Resistor elements (resistor grids) itself are made
of stainless steel (AISI 304).
The neutral terminal U and the ground terminal V
are performed on porcelain insulators. The cable
entry is provided from below.
Optionally, the terminal U as outer cone
connector 400 or 630 A can be provided.
Following material is installed inside the housing:
Compact resistor element as a resistor block of stainless steel grids, which is based on supporting
bolts with attached ceramic insulators.
Supporting insulators as carriers for the resistor blocks, which comply with the relevant insulation
class. On the resistor an engraved nameplate / label is attached.
Overall dimensions correspond to the drawings, which are added to the offers generally.
Optionally, the resistor can be delivered with an one- or three-pole vacuum switch, with a sectionalizer
and / or a variety of accessories, such as current transformers, protection relays, lighting,
thermostatically / hygrostatically controlled heaters etc.
