NGR Neutral Grounding Resistor, Stainless Steel Grid Resistor types, High Power Capacity
Structure:
1. ZENITHSUN stainless steel resistor is made of low temperature
coefficient alloy sheet. According to the requirements of
customers,stamped into different sizes and shapes, and
combined in series and parallel.
2. Resistors sheets are separated by insulating material or
fixed by shaped high-temperature resistant porcelain pad.
3. The leading out are stainless steel terminals, which can be
tapped for customer connection.
Feature:
1. Reliable
2. Robust
3. Compact / light
4. Limited thermal drift on resistance value
5. Cost effective
6. High Power Capacity
7. Resistance value low to 0.01Ohm
Application:
ZENITHSUN Stainless Steel Resistors are suitable for AC or DC high
current applications.
The most common application fields are motor control, braking and
speed regulation, and can also be used for neutral grounding,
harmonic filtering and load banks solutions;
The rugged structure is especially suitable for heavy equipment in
industries with high impact and strong vibration, environment, such
as port / wharf industrial control crane, mining equipment, oil
drilling, construction tower crane and other application
fields of lifting, speed regulation, dynamic braking or long-term
load.
The unit is an ideal product for continuous use under extreme
conditions (high vibration, high temperature and corrosive
environment). The metal sheet can ensure the continuous use
and the minimum resistance value fluctuation.
ZENITHSUN can provide customer with personalized design to
better meet your needs, so as to greatly save space and cost.
