Detailed Product Description

3000 Watts, Neutral Grounding Resistor Element, for dump load, brake, build up NGR or Loadbank Neutral Ground Resistor

 

Structure:

1. ZENITHSUN ZB series Plate-shaped Wirewound Resistor is made of nickel chromium,constantan or new constantan alloy wire and other high-quality alloy wires wound on the iron plate with surface electroplating treatment, aluminum plate with surface anodizing treatment or mica plate. Ceramic devices are used to separate the winding wire from the base plate, so that the winding wire can drive over the base plate evenly and regularly, playing a good role in fixation, insulation and heat dissipation.
2. Aluminum plate or iron plate matrix has no fixed form and can be made according to customer requirements, breaking the limitations of the industry.

 

Feature:

1.ZENITHSUN ZB series Resistors have stable resistance,small change rate,high power,strong overload capacity.
2.The corrugated winding mode (increasing resistance and eliminating parasitic inductance), and non-inductive winding mode can be realized, which can not only eliminate the parasitic inductance of the resistor, but also improve the heat dissipation. 
3.It can also be flexibly changed according to customer requirements to make a single resistor with more than 2 resistance values or multiple resistors in series and parallel.

 

Application:

ZENITHSUN ZB series 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.
