6600W 35Ohm Neutral Grounding Resistor for generator, Industrial Metal Grid Brake Resistor
Structure:
1.Shenzhen ZENITHSUN Electronics Tech. Co., Ltd 6600W 35Ohm
Resistor is made of low temperature coefficient chromium alloy
stainless steel grid sheet. According to the requirements of
customers, stamped into different sizes and shapes, and
combined in series and parallel.
2.Resistors sheets elements are separated by insulating material or
fixed by shaped high-temperature resistant porcelain pad, which
provide good insulation.
3.The terminals are also stainless steel materials.
Feature:
1.Enough Power Capacity, can withstand 6600W continuously.
2.Robust,long service life.
3.Compact / light to save space.
4.Limited thermal drift on resistance value ( stable resistance
value even at high temperature).
5.Cost effective
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.
