Cables

Signal cable Mesit designed cables for: signalling, remote monitoring and remote control, measurement and instrumentation thermocouples extension cables, electric end electronic data-processing industry and low voltage power distribution and nuclear power plant (resistant to the radiation and L.O.C.A. conditions). Some of these cables have been especially developed according to the most recent international standards: IEEE 383; 323-IPCEA-BS-IEC-VDE. Relevant know-how has been developed in the specific field of qualification requirements and system, which can be offered to the engineering organisations and plants reliability. A plant qualification Data package can be developed upon review of the environmental and accidental plant conditions as established by Customer. When such a complete review is not required, consulting services on detailed problems can be furnished. Test programs and trials can be developed for insertion in the equipment and system specifications, test can be performed on potential and effective supplies. We invite enquiries in this very specialised field, where the basis for an updated know-how is the active presence of our experienced specialist Group in the development and production of sophisticated I. And C. equipment and cables including any spare-parts requirements.

Extension cable We provide a wide variety of insulation systems for thermocouple extension grade cable with multiple twisted pairs. All thermocouple extension wire and cable can be manufactured for eject electromagnetic interference. The twisting of pairs will protect against electrostatic interference. Lead covering can be provided. If additional mechanical protection is required, armouring in the various types of metallic shield braids, wire or tape can be provided. We utilize all the basic up to date characteristics of available insulation-jacketing systems.

With one, three multiple pairs, suitable for use in computer and inherent safety system circuits are produced to Standards or Customer specifications for the same temperature range as required. Production is made under a controlled quality system. Edition compliance may be provided.

Mineral insulated electric heat tracing system Mesit mineral insulation heating cable is made of one or twinned cores for resistance insulated with magnesium oxide high compressed, the whole contained within a continuous copper sheathing (eventually with an additional covering of a thermoplastic material), stainless steel or Inconel if requested. The multipass reduction construction process consist in subsequent wiredraws alternated with homogenous and proportional deformations of the elements making up the cables (sheathing, insulation and conductors) which behave like a perfectly elastic material. The practicality high specific capacities are possible. It does not request any maintenance once it is installed, it can be easily bent and due  to its small diameter it can adapt itself to any kind of support without any possible damage. The mineral elements incombustibility to high temperatures. MI cables allows you safety advantages because the metal sheathing guarantee a permanent earth discharge. In the explosive danger areas the mineral insulation heating cable, fitted with the appropriate connections, is accepted by all national and international standards. Simple automatic heating control is precise and cheap. The endurance of the inorganic materials which make up the cable  do not allow the wear of the electric and mechanic characteristics. In the nuclear plants the mineral elements with which the cable is made up allow for its use in surroundings of high radioactivity.

With the mineral insulation heating cable is possible to solve nearly all the heating problems in all industrial fields:

• petrol and chemical industry for heating and keeping in temperature ducts, thanks, valves, pumps, instruments, etc.;

• gas industry for heating water ducts of fire services and gas ducts in order to prevent freezing of hydraulic gasometers;

• nuclear industry pre-heating and keeping in temperature sodium circuits and pressurised water;

• electric plants for heating naphtha ducts and water ducts and for heating up instruments;

• freezer industry anti-freezing protection of the floors of freeze chambers and the doors of the chambers;

• civil application and transport for heating of tankers, containers and railway crossing. Building heating of dwellings industrial buildings, hospitals. Heating of terraces, drains and roofs for preventing freezing. Heating of covered swimming pools. Heat for drying cement and pre-drying of fire-bricks. To stop snow  accumulation and ice formation on roads , access ways to garages, bridges and viaducts, parking, open air stair cases, football pitches, aeroplane landing pads;

• horticulture and floriculture heating of greenhouses, warm beds and benches for plant cultivation.

Mesit technical assistance organisation and the long experience acquired in a high number of plants allow us to offer our clients a series of first class services: design, engineering, construction and control under guarantee of quality, supply and set up of the cables and of the control systems of the plant, heat-insulation supervision, testing and technical assistance. The whole implies total responsibility on our behalf services supplied, either total or only partial.
