Digital Type Linear Heat Sensing Cable for outdoor use –CR/OD Type–UL Approval
Digital Type Linear Heat Cables for outdoor use
Description:
OD Type not only has good UV resistance and good weather resistance, strongly recommended for outdoor using even under bad weather conditions,but also with high performance of acid resistant, alkali-resistant, salt spray resistant.
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.
The black color one is for outdoor use .
