Electric heating cable is easy to install, use and maintain; easy to automate management; no environmental pollution; long service life and other characteristics. It has been widely used in people's daily production and life, and the use of electric heat tracing is convenient for people's production and life. Perform proper maintenance.
So what problems should we pay attention to when maintaining electric heating cables?
1. First of all, after the installation of the electric heating system, we must measure the insulation resistance of each loop before the first use. The electric heat tracing system should be put into operation in batches to avoid the shock caused by the excessive starting current, which will lead to the burning of the heating cable, resulting in damage to the heating cable and shortening the service life of the heating cable.
2. During the use of electric heat tracing, we need to check the heating cable regularly, and perform corresponding testing when the use time reaches a predetermined time interval. If there is an abnormality in the heating cable, it should be dealt with in time to avoid a larger accident.
3. Preventive inspection of the faulty circuit in the use of electric heat tracing: mainly check the protective layer, the protective layer needs to check whether the protective layer outside the thermal insulation material of all the heating cables is damaged, and whether the sealing silicone at the seam of the protective aluminum skin is in good condition, Whether the thermal insulation layer is loose or falling off, the damaged parts such as the protective layer should be replaced in time to prevent the heating cable from malfunctioning in use and affecting the normal operation of the entire heating system.
4. At the same time, when maintaining the electric heating system, it is necessary to pay attention to the inspection of all junction boxes in the heating system, and at the same time, check whether the junction points and thermostats on each bushing in the skid block are corroded by corrosion and moisture. Replace damaged or deformed junction boxes and temperature control facilities.
5. For the heat tracing system that is started seasonally, before the heat tracing system is started, we conduct the electric heat tracing control, power distribution system,
Check and troubleshoot the wiring method of the electric heating cable, external insulation layer, etc., to ensure the normal operation of the heating system.
The above-mentioned testing steps of the heating cable are the specific methods given by our company, as the user's reference when testing, if the user is interested in the selection of the heating cable
