Digital Type Linear Heat Sensing Cable –Conventional Type –UL Approval
MD Series Digital Type Linear Heat Cables--- Conventional Type for Indoor Use
Description:
This type of Linear heat detection cable is the most widely indoor used with strong stability.
Technology Principle:
The polymers between the two conductors will break down at specific fixed temperature allowing the conductors contact, the short circuit will intimate the alarm.
Introduction of Linear Heat Detection Cable:
Intertwisting two rigid metallic conductors which are covered by NTC heat sensitive material, with insulative bandage and out jacket, here comes the digital type LHD Cable, and the different models depend on the variety of materials of outer jackets to meet different special environments.
