LSR self regulating heating cable is an exceptional heating cable. Constructed of a semi-conductive heater polymer（also named as “PTC”） extruded between parallel bus wires with the addition of insulation layer. Suitable for both metal and non-metal piping systems, storage tanks and equipment to provide anti-freeze protection, except for those of of steam purging.

As the heating elements are parallel to each other, it can regulate its heat output automatically all along its length according to the change of the ambient temperature, at low temperatures,the polymer shrinks, there are many conductive paths, allowing current to flow between conductors, on the contrary, as temperature increases, it disconnects the circuit to reduce heat generation automatically, then it loops depending on the change of the temperature.

In some applications, for maintaining a precise target operating temperature, use of a thermostat is strongly recommended.

In addition to the advantages of self-limiting temperature, it can wrap itself without the danger of overheating. Furthermore, due to the parallel structure design, this high temperature cable can be cut in length according to different needs.

LSR-J is the basic low temperature heating cable type, with the Max.maintain temperature up to 65℃（149°F）, while the Max.exposure temperature is 85℃ (185°F). Generally used in places where there is no explosion-proof or anti-corrosion requirements, and the environmental humidity is not high.

LSR-P/F is enhanced with an additional aluminum-magnesium alloy braid(tinned cooper for option), sheathed by a fluoropolymer out jacket. Compared to LSR-J, it has a good performance on anti-corrosive, also with characteristic of explosion-proof, ideal for places with explosion-proof requirements, especially chemicals, power supply and other places need corrosion resistance.

Advantages：

1. Energy saving: Due to the unique PTC property, the cable adjust the output power respond to ambient temperature.

2. Easy installation: PTC semi-conductive matrix is composed of the infinite parallel connection of carbon particles, allowing it to be cut into the exact length required.

3. Long service life: A lower starting current and attenuation rate ensures our cables provide you a longer service life.

4. Safety for use: Can be overlapped by themselves without the danger of overheat or burnout.

5. High quality with low cost: self- regulating, easy operation, low cost to maintain. No recycled material used, all the components are manufactured by our own factory, which means better quality and competitive cost for you.

Have you ever got bothered by the same difficult troubles?

When the cold wave hits in freezing winter days, snow will appear on roads and slopes, it is easy to slip. A large area of road icing will bring danger to people's travel safety, and also leads hazards to your vehicles.

When the heavy snow on the roof is too deep and the gutter is totally frozen, what makes it even worse is that the water pipes get blocked from frozen too. of course, all of these will surely bring huge potential risk to your house safety.

So, is there any good way to solve the problems brought by the snow and ice?

Highly recommended to use a LSR self-limiting heat tracing cable for the snow melting. It can help you to solve the troubles caused by the bad weather, keep the road and roof unobstructed, free from icing, in addition to the perfect performance on freeze protection, it can also save electricity as much as possible for you, which achieve the best economical and practical effect.

Due to the unique self regulating designed, this electric heating cable can adjust the operating power according to the change of the ambient temperature automatically. Which means when the ambient temperature is getting low, the heating power will increase automatically; when the ambient temperature rises, the increase of the electric resistance will automatically reduce the heating power output, by which our electrical heating cables could help you to achieve the purpose of energy saving smartly.

Since the electric heating cable is parallel structured, It can be cut into any length arbitrarily, furthermore, the installation is rather convenient. This heat trace wire can be bend, moreover, it can be overlapped by itself without the problems of overheat and burnout.

Never use recycled materials, only virgin raw material applied, which ensures our electric heat tape keeps the highest industry standards.

The traditional starting current is usually 3 times of the working current, while the initial starting current of our heating cables is extremely lower, which means our products have a longer lasting service life.

Over 85% shield covered, 100% quality inspection guaranteed, All of these make our heat trace cable safer and much more durable.

The maximum heating temperature of our LSR cable can reaches at 65℃, suitable for all applications of snow melting, freeze protection and other industrial demands.
