Product introduction:


Silicone rubber parallel connection electrical heating band is also called “high-value PTC silicone rubber electrical heating band”, it is a new type of electrical heating tracing band using high-temperature flame-retardant silicone rubber as insulation method, it has high electrical insulation, good flexibility and softness, especially suitable for anti-condensing, anti-freezing of various complex pipelines and valves, etc., it is an ideal Product. Especially its specific weight only accounts half of the fluorine plastic, its price is only 1/4~1/3 of fluorine plastic, replacing the fluorine plastic in the engineering application by greater advantages. The use of high-value PTC silicone rubber electrical heating band in the same effect conditions of fluorine plastic electrical heating band, reduces the costs, and improves market promoting.
High-value PTC alloy silicone rubber electrical heating band produced by the company has gained National pragmatic new patent certificate, its patent series number is ZL03203202.1, the certificate number is:602708, also included in the National scientific enterprise technology innovation fund and torch plan.

Working principle:


The power busline of silicone rubber parallel electrical heating band is two root or three root parallel insulation copper wire, wind PTC alloy wire on the silicone rubber skeleton layer, the PTC alloy electrical heating wire is intersected by each certain distance, that means connect “heating segment” with the busline, forming a parallel connection resistance, once the busline is powered, all parallel
resistance heats, thus forming a continuous electrical heating band.
Silicone rubber parallel electrical heating band has a certain nominal power per meter, the longer the electrical heating band, the larger the total output power, but due to the heating elements by using PTC alloy wire, thus, it itself has the feature of output power adjusting according to temperature change, and the electrical heating band uses silicone rubber as the insulation material, thus, the band body is soft, easy to install. The electrical heating band can be arbitrarily cut according to the actual length needs.
