Product Name:Series Resistance Constant Wattage Heating Cable RDC


Short Introduction:

Series Resistance Constant Wattage Heating Cable RDC is used for long pipe heating cable freeze protect,temperature maintain.The max length of RDC can use is about 1500m with only one connection. It can save a lot of connection work and junction box. HRRDC series connection constant wattage heating cable use the core conductor as the heating element,when the core conductor connect to power supply.


Application
RDC series connection constant wattage heating cable use the core conductor as the heating element,when the core conductor connect to power supply,the core conductor will send out joule heat,because unit length constant power heating cable 's current and resistance is equal to all length heating cable.so the heating value of each unit is equally.not result in the power of terminal end is lower than beginning end with the increasing length of heating cable.so this type is suitable for long pipeline and large diameter pipeline’s heat tracing and heat preservation.power supply by one power point.

Notes:
Longline heating is required to ensure that liquids are transported cost-effectively and safely over long distances. In the absence of longline heating, the following problems could result in significant environmental and property losses:
1. Liquids becoming too viscous
2. Gases condensing
3. Liquids freezing resulting in catastrophic pipe failures 

Longline heating applications have several challenges, such as:
1. Large pipe diameters
2. Elevation changes along the length
3. Remote locations
4. Lack of power availability along the length

For pre-insulated pipes, additional challenges include:
1. Alignment of channels
2. Lack of insulation at the pipe joints
3. Pulling long lengths of cable through the channels
4. Lack of accessibility of connection kits
