The risk of Overheat and/or Fire conditions on Power Transformers and Generator sets remain high - even where regular maintenance programmes are operated and where shielding, grounding and lightning arrestor devices are installed.

Primary sources of fires include over-heating/ignition of diesel, dirty insulators, insulation deterioration and lightning strikes on transformer units.

The most effective detection of the overheat condition (pre- combustion) or the fire itself is by DIGITAL LINEAR HEAT DETECTION.   A combined detector and cable which monitors local temperature changes, and is able to operate continuously within adverse environments and areas of limited access and surveillance. The fixed temperature (non length dependant) based system can be installed either directly onto the device it is protecting via plastic cable ties and mounts, or to very local extinguishing pipework where installed, and should be routed around all sides of the transformer or generator at BOTH top and bottom levels in order to maximise protection and ensure fastest response times.

Linear Heat sensor cables supplied and/or manufactured by PROLINE PROTECTION SYSTEMS LTD, are colour coded for alarm temperature verification, flame retardant, corrosion and abrasion resistant (as standard), and offer U.L. listing or F.M. approvals as a minimum.  When used in conjunction with an optional dedicated interface unit they can also provide alarm point location facilities - of particular advantage on pre-combustion detection situations where no visible flame exists.


Digital (LHS) & Analogue Linear Sensing

The means to locally monitor for temperature changes (rise or fall) at "point of risk" and at ANY /ALL locations along an installed length of temperature sensitive cable - regardless of environmental conditions.

Fibre Optic Linear Temperature Sensing

Line detection of temperature change and rate of rise along multi -kms lengths of small diameter fibre optic cable. It provides high performance near real time temperature Sensing and Alarm functionality with standard communication interfaces.

Proline 'Nero' Water & Moisture Detection

Rapid detection of the smallest of leaks within Industrial, Commercial Environments by a recoverable cable. Designed to provide 24 hours/day x 7 days/week continuous monitoring of areas where even the smallest of leaks can prove disastrous. Essential where undetected leakages can cause serious damage to today’s complex electrical, communications and computer networks.
