Protectowire thermal cable: 15 years of success in the Russian market.
The economic growth rate in Russia is increasing every year, the country's GDP is growing, which entails the construction of new industrial and mining production areas. Requirements for projects, for the strength of the objects being erected and, as a rule, for fire safety are increasing. In many cases, the installation of conventional fire alarms (smoke, heat, combined, etc.) at industrial facilities is not possible due to their design features (belt conveyors, shafts, tunnels, etc.), as well as the inability of conventional alarms to ensure normal operation, which is due to the physical state of the environment (low temperatures, humidity, dust, chemical reagents, etc.). For such non-standard and hard-to-reach objects, it is always difficult to choose the right, reliable, compliant with current fire safety standards, as well as certified and cost-effective solution. We can say with complete confidence that such a solution is a linear heat alarm — Protectowire® thermal cable.Why Protectowire? Because Protectowire, Inc. has been the world leader in the production of linear thermal fire detectors for 70 years. This is a world-famous brand — a guarantee of quality and reliability. For 15 years on the Russian market, Protectowire® thermal cable has proven itself from the best side. Thousands of kilometers of Protectowire® thermal cable have been installed throughout Russia. Protectowire® thermal cable protects MEGA, IKEA hypermarkets in St. Petersburg, Rostov, Krasnodar, Lefortovo tunnel (Moscow), oil storage facilities in Novorossiysk, nuclear industry facilities in Angarsk, cable channels and conveyors at the automobile plant in Tolyatti, mining facilities in Sakhalin, etc.Let us recall that the thermal cable allows you to detect the source of overheating anywhere along its entire length. The linear heat detector (Protectowire® thermal cable) consists of two steel conductors, each of which has an insulating coating made of heat-sensitive polymer. The conductors with the insulating coating are twisted to create mechanical stress between them, then covered with a special protective sheath and placed in a braid to isolate them from adverse environmental conditions. The principle of operation of the thermal cable: when the threshold temperature is reached under the action of the pressure of the conductors, the insulating coating made of heat-sensitive polymer is destroyed and the conductors come into contact with each other. To trigger the signal, there is no need to wait for a section of a certain length to heat up. The Protectowire® thermal cable allows you to generate an alarm signal when the temperature threshold is reached at any point along the entire length of the cable with low inertia.
There are currently four types of thermal cable, differing from each other in model type and material from which the outer protective braid is made, for use in a wide variety of environmental conditions.
ЕPC — EPC type heating cable has a very strong extruded outer PVC protective braid, providing complete and reliable protection of the cable in almost all environmental conditions. The cable of this series is universal and is well suited for both industrial and commercial use. The heating cable is enclosed in a fire- and moisture-resistant outer protective braid, maintaining excellent flexibility at low ambient temperatures.
EPR — EPR series thermal cable has a durable, flame-retardant, ultraviolet-resistant polypropylene outer braid. It is designed for a wide range of industrial applications and is characterized by high elasticity, resistance to abrasion, weathering, and exceptional reliability at high ambient temperatures. EPR series thermal cable is more suitable for operation at high ambient temperatures than EPC thermal cable.
TRI — TRI-Wire™ thermal cable is a unique thermal detector that can separately generate a pre-alarm signal and a fire alarm signal, depending on the set temperature thresholds. The thermal cable is enclosed in a durable, flexible, moisture- and fire-resistant outer braid made of polypropylene, resistant to most common chemicals.
XLT – The XLT type of heating cable has been specially designed for operation at extremely low temperatures, making it ideal for use in cold storage warehouses, commercial freezers and unheated storage areas. The XLT outer jacket provides excellent overall performance characteristics – low moisture absorption, resistance to most chemicals and provides excellent performance at low temperatures.
XCR is a new product on the Russian market. The XCR series thermal cable is enclosed in a high-quality outer fluoropolymer sheath. This type of detector was specially developed for facilities whose protection requires the use of reliable, high-tech and environmentally friendly equipment. The main feature of the XCR series thermal cable is a fluoropolymer fire-resistant sheath with reduced smoke and gas emission, providing the highest mechanical resistance to abrasion in a wide range of temperatures. The sheath also protects the heat-sensitive polymer from the effects of a wide variety of acids, alkalis, organic solvents and simple gases. In addition, the sheath is resistant to sunlight (including UV radiation), as well as to various weather conditions. At extremely low temperatures, this type of thermal cable demonstrates the best performance in comparison with other types.
The complete classification of the thermal cable is presented in Table 1.
