Did you have the following confusion when you bought resistors?
  • Resistors smoking,
    gives off a pungert smell?
  • Resistance open circuit,
    burn out,
    even explode?
  • Too hot?
    Resistance valve varies greatly?
  • Suppliers'service
    attitude are poor?


Let you have no worries!



Wirewound Resistors

ZENITHSUN-Power Resistors and Load Banks solution provider

Advantages of Ceramic Tube Wirewound Resistors

Low Temperature Coefficient Alloy Resistance Wire

Resistance wires are evenly distributed,with thicker wire diameters,which are not easy to burn and can withstand greater impact power.

Corrugated Wirewound Process

effectively increase the heat dissipation area & reduce inductance.

Ceramic Pipes with Low noise

Ceramic Pipes with good quality, resistant to high termperature & Vibration & Humidity.

Durable Insulation paint-coating

Non-inflammability paint-coating,
protect the resistance wire from
oxidation & enhance
heat dissipation.

Thickened Bracket,

Thickened galvanized or stainless steel bracket,more reliable and stable.

Built-in ripple braking resistors

Aluminum housed resistors, edge-wound resistors, stainless steel gride resistors are available.

Force Air Cooling System

Powerful fans, fast heat dissipation, quiet operation

Portable Design

handles, fly rings, casters for easy move

Baking finish metal enclosure,corrosion resistant

1.5-1.8mm thickness,more reliable structure,
Detachable design, easy for internal cleaning and maintenance
Huge production capacity guarantees the delivery time
