With desire to cement our reputation in the market, we are engaged in manufacturing and importing Linear Heat Sensing Cable. Offered cable is designed to provide early detection of fire conditions and overheating in circumstances where other forms of detection would not be viable. Offered cable has an overall protective jacket / sheath LHDC Digital may be used as a simple switch to operate a relay. This cable is compatible with many existing zone monitors / control equipment.

Features:

Early Detection of hazards at temperatures well below flame point
Fixed Alarm Trigger Temperature
Rugged construction

Other Details:

Extensive single zonal lengths of the LHDC Digital may be installed with the ability to trigger alarms for hot spots occurring on very small sections of the overall cable
The Linear Heat Detection Cable may be employed in a wide variety of applications but is particularly suited where there is harsh environmental condition, a physical or hazardous maintenance access constraint to protect the area, and / or a requirement to cost effectively install detection in close proximity to the risk(s)
The primary mechanism of LHDC is that the inner core insulating polymer is specially formulated such that it plasticizes at a specific temperature

Cable Construction:

The Digital Linear Heat Detection Cable comprises of a twisted pair twin core cable
Each core is of tinned copper coated spring steel and has a special heat reactive polymer insulation
The cable has an overall protective jacket / sheath
LHDC Digital may be used as a simple switch to operate a relay etc
However in most installations the minimum requirement is that the LHDC circuit is monitored for disconnections by means of EOL device and an appropriate fire alarm channel or address loop interface unit

Applications:

Cable Tunnels, Ducts & Mezzanines
Escalators & Moving Walkways
Petrochemical Storage Tanks / Rim Seal Protection
Paint Shops & Spray Booths
Conveyors - Coal, Wood Sulphur etc
Ceiling Voids & Attic Spaces
Road & Rail Tunnel Carriageways
Nuclear Reactor Plant Areas
Refrigerated Stores & Cold Rooms
Electrical Control & Switchgear Cabinets
Warehouse High Rise Pallet Racking
Oil Rigs & Off Shore Platforms
Fume Cupboards & Glove Boxes Grain Silos & Agricultural Storage
Road / Rail Vehicle Engine Compartments
Steam pipe Leeks & Trace Heating Faults
Product Lines - Flanges, Valves & Pumps
Computer Room under Floor Cable Voids

In line with clients' variegated requirements, we bring forth a distinguished collection of Analogue Linear Heat Detection Cable. Due to the integrating effect of these cable is able to detect either a hot spot or a lower level of temperature increase over its total length. Our offered heat detection cable senses temperature variations by continuously monitoring the resistance of specially doped negative temperature coefficient (N.T.C.) polymeric insulation.

Features:

Monitors precise point of risk
Recoverable after operation
Sensitive to small temperature variations
Analogue Linear Temperature Detection:

Analogue cable senses temperature variations by continuously monitoring the resistance of specially doped Negative Temperature Coefficient (N.T.C.) polymeric insulation
A change in temperature produces a relative change in resistance between the two loops within the sensor cable – as temperature increases, resistance is lowered
This change is monitored by an LHD control unit, which actuates an alarm signal at a pre-determined level
The integrating effect of sensor cable enables it to detect either a hot spot or a lower level of temperature increase over its total length
Linear Heat Detection System:

Provided the sensor cable has not been directly subjected to temperatures greater than 120°C for excessive periods, it will recover to an alert condition after activating an alarm
Upon destruction, the cable fails permanently into the alarm state
Benefits:

Flexible in installation
Recoverable after operation
Monitors precise point of risk
Sensitive to small temperature variations
Mechanical/environmental protection options
Applications:

Rack storage
Escalators
Cable trays
Conveyors
Floating roof tanks
Covered car parks
Other Details:

At one end of the sensor cable, the four conductors are connected to an LHD control unit (optionally via a junction box)
At the outer end, the conductors are joined and hermetically sealed to form two loops
Both loops are continuously monitored for open and short circuit faults
A breakage or disconnection of either loop initiates a fault signal in the control unit
Extra mechanical or environmental protection can be provided by the addition of a nylon coating or bronze braiding
