Industrial heating equipment needs to adapt to diverse temperature working situations, i.e., low temperature constant temperature processing below 100℃, and high temperature industrial heating above 3

In daily operation, the most common electrical problem of industrial electric heating tubes is terminal wiring failure, including poor contact, wire falling off, terminal oxidation and short-circuit l

Modern industrial manufacturing has increasingly diversified and specialized heating needs, with a high variety of non-standard equipment, special-shaped areas, and unique process factors needing targ

Many problems occur often in industrial heating projects, such as fluctuating heating temperature, limited element service life, and frequent shutdown of equipment due to overheating or insufficient h

It is usual to be confused about how to select parameters for buying industrial heating elements, especially to match the watt density and temperature grade of cartridge heaters. Many heating system f

One of the most common concealed electrical problems in industrial heating shops is voltage unbalance in three-phase, typically resulting in unexplained heater tube burnout, unpredictable thermal outp

Industrial heating transformers are used for centralized power supply to all tubular heating elements and thermal processing equipment. Their operational stability is a direct determinant of overall s

Three-phase voltage unbalance is bound to cause the increase of current unbalance in industrial heating circuits, and is the main reason for the frequent failure of heating tubes and the damage of aux

Most industrial heating firms pay attention to heating tube thermal efficiency and equipment performance, but ignore the substantial energy loss caused by three-phase load unbalance in four-wire power

At present, a lot of nonlinear equipment and variable frequency equipment are used in the industrial heating workshop, which is easy to cause three-phase imbalance and negative sequence harmonic inter

The main artificial source of three-phase imbalance in industrial heating systems is unreasonable concentrated load wiring. In workshops, the wire design sometimes aggregates many single-head heating

Many old industrial parks and old manufacturing buildings have intrinsic flaws of backward low-voltage distribution networks, so the three-phase load unbalance becomes a recurring problem for the func
