NGR 20KW 100Ohm Neutral Grounding Resistor, Neutral Earthing Resistor
Shenzhen Zenithsun Electronics Tech. Co., Ltd presents the new BXG3 series for applications in extreme environments.
The stainless steel power resistors come with high power capability up to 20kW at 40℃ and a high operting temperature range of -25℃ to +250℃.
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
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.
