Alternative Replacement for HVR high voltage high power high energy ceramic resistors.
In 2020, HVC develop new type ceramic disc type high voltage resistor, which using Zinc oxide base material.This new type of ceramic resistor with many advanced performances compare to traditional metal shell type high power resistor, also with much higher surge absorbed ability.
Compare to HVR's original high power resistor, HVC items also get approval by some fast train and smart grid market customers. They required the high power resistor manufacturer to offer them disc only(mostly for power electricity machine client) and also assembly type,(majorly for transportation equipment manufacturer), welcome to give your design idea and your existing HVR drawing, our engineer may offer a professional solution.
The performance of zinc oxide-based high energy resistance of our company
Zinc oxide ceramic linear resistance is made of composite ceramic resistance inorganic materials, using advanced new ceramic technology, which has incomparable characteristics of traditional resistance. It has unique advantages in high frequency, high current pulse circuit, high energy absorption circuit, nonintermittent power supply circuit, especially in the presence of impact energy, peak power, high voltage or low inductance and other conditions The composite ceramic resistor can provide you with a simple and economical solution to solve the industry pain point problem. The product has the advantages of instant absorption of great power, moisture-proof, dust-proof, small size, safety, long life and so on. In terms of performance, it is far more than the carbon black composite resistance at home and abroad. It is a new generation product, which is beneficial for customers to develop new products and create higher value for users
1. High power: the resistance value of the product can be adjusted, and it can withstand high current, and it can be used as high power resistance
2. Large energy tolerance: the instantaneous energy absorption per cubic centimeter is more than twice that of the clay carbon black ceramic resistance produced in Europe; there is no failure phenomenon of film type and wire-wound type resistance, and the reasonable structure makes the energy absorption distribution more uniform;
3. No inductance: about 0.4 uh, equivalent to the inductance of the same length of wire, suitable for high frequency and ultra high frequency environment;
4. High voltage resistance: it can be used in EHV and UHV power transmission system with high power and large heat capacity, and can withstand short-term overload and peak current;
5. Small volume: 1 / 10 - 1 / 2 of the volume of metal resistance and clay carbon black ceramic resistance, suitable for various instruments and equipment;
6. Stable performance: in the long-term use, the change rate of resistance of European clay carbon black ceramics is more than 1000 times, while the change rate of this product is within the design range, with little change;
7. Resistance to humidity, corrosion and oxidation: it can work in extreme environment such as dust, water, oil, high cold, ocean and space;
8. Anti vibration: reasonable structure makes the product have anti vibration function;
9. Safety: evenly absorb the energy in the resistance body to prevent explosion;
10. Long service life: it is a vicious circle phenomenon in the use of carbon black resistor, which is more than 10 times of the service life of carbon black resistor produced in Europe (30 years service life)
