Digital Type Linear Heat Sensing Cable EP(Explosion Proof) Type–UL Approval
Digital Type Linear Heat Cables Explosion Proof Type --EP Type
Description:
EP Type--- Explosion Proof Type,Two main application environments: harsh EMI environment and explosive hazardous environment. The outer jacket of this type is protected by woven metal mesh with good performance of anti-EMI and eliminating the surface static of the LHD. We can use this type LHD in explosive hazardous environment with safety fence. EP Type is intrinsic safe type(Explosion Proof Type). During the installation, please make grounding connection of the woven metal mesh. Used in harsh EMI environment, single end grounding connection or double ends grounding connection should be specified after analysis of the interference sources.
Applications:
●Cable tray, Cable tunnel, Cable trench, High-voltage cable.
●Highway tunnel, Subway tunnel, Dam.
●Rail tunnel, Utility tunnel.
●Convey belt, Coal conveyor, Coal storage yard.
●Oil tank, Gas tank, Oil convey pipeline, Gas pipeline.
●Warehouse .
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.
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.
