Power resistance and resistance box system solution providerManufacture of national brands of power resistors and resistor boxes

1. Product Features:

1) High power, high precision, corrosion resistance, high temperature resistance, humidity resistance, low noise, high stability.

2) One of the characteristics of glazed resistor is that the surface is glazed. This glaze refers to the glass glaze sintered by high temperature on the resistor surface, which makes the resistor surface smooth and moisture-proof, and the resistor is more resistant to high temperature, pollution, environmental protection and safety.

2. Product Structure:

1) Glazed resistor is also called enameled resistor, which is one of wire-wound resistor. Because of its special structure, it is different from the conventional wire-wound resistor, It is characterized by the T-groove at both ends of the porcelain tube. After the resistance conductive sheet is directly inserted into the T-groove, the port is sealed with inorganic materials, the starting point of winding wire is welded firmly at the root of the conductive plate, and the high stability resistance alloy wire is wound on the porcelain tube evenly, then coated with vitreous enamel at high temperature.

2) The glazed resistor adopts high quality alloy wire material and brass welding, which effectively improves the welding reliability and the qualified rate of finished products.

3) The customized special conductive plate is closely combined with the T-groove of porcelain tube, which increases the mechanical strength, avoids the bad phenomena of serration and pimple at the bottom of the traditional glazed resistor conductive sheet, and greatly improves the appearance quality of the product,.

4) Surface vitreous enamel is made by sintering at high temperature, which makes resistors more corrosion resistant, high temperature and humidity resistant, and is suitable for high temperature, corrosion and other harsh industrial control environment. If the winding is corrugated, it can eliminate parasitic inductance of resistor and improve the heat dissipation of resistor, extend the service life.

5) The surface vitreous enamel can be made in green or coffee color according to the requirements of customers, and other requirements can be customized according to the customer's needs.

3. Application Fields:

Glazed resistor is high temperature resistant and moisture-proof. It can be widely used in DC or low frequency AC circuits of various electrical equipment and electronic instruments for voltage reduction, voltage separation, shunt or load resistance. In rectifier power supply, it is used as filter resistor, step-down resistor, and as voltage divider and shunt in instrument.
