Professionals of ENERGOCOMPLECT LLC have substantial experience in various fields of power industry.

Often we can help, where other suppliers or engineering organizations have already refused to offer a complex process engineering solution.

Centrifugal Bubble Unit

CBU is a unit for perfect mixing of gas and liquid.

Principle of CBU operation is based on gas flowing through rotating liquid layer held in turbulence chamber by gas flow and centrifugal force with formation of a bubble column during mixing.

It can be used as: scrubber, absorber, desorber, open-type heat exchanger, chemical reactor in production processes.

CBU can be used in various fields: mining and processing, power industry, metallurgy, chemistry, petrochemistry, oil refining, agriculture, building materials manufacture, mechanical engineering etc.

Solutions for Electric Power Transmission

When it comes to power solutions, we can offer our expertise in use of innovative most advanced compact cables. Technologies applied in manufacture of these cables make it possible to transmit high currents over a line, as well as to significantly cut down maintenance costs of overhead lines.

The backbone of the compact cable technology is three factors:

  • section shape of upper layers of wires is not round like in traditionally used cables, but Z- or trapezium-shaped. This property of the cables gave them their name: Z-cables;
  • potential for use of a core made of polymer materials - epoxy resins, glass fiber and carbon fibers;
  • application of differently directed layers - when upper layers of wires are twisted in opposite direction to the lower layer.

What are the advantages of all told technical solutions?

  • almost no internal corrosion;
  • decreased amplitude and intensity of line-wire dancing, decreased level of metal fatigue inside the cable due to self-damping;
  • improvement of mechanical stress from line-wire dancing on supports and, as a result, increase of service life of an overhead line;
  • reduction of losses during electric power transmission;
  • reduction of noise level and, as a result, improvement of performance criteria in populated areas;
  • no additional costs during installation, fixtures at hand can be used;

And if we are considering the use of a core made of composite materials, then these cables:

  • allow for doubling rated current and increasing transmission capacity of a line up to twofold, including varying this parameter with a diameter of the composite core;
  • allow for reducing the line losses and airborne emissions related to them by 20-30%;
  • are lighter than aluminum steel cables of the same effective section by 50-60%;
  • ensure smaller amount of deflection which provides for increase of length of line spans and use of lower anchor towers or fewer supports;
  • no corrosion;
  • allow for reducing the load on supports due to ice formation and wind loads which increases reliability and lifetime of an overhead line.

Heating

Heating cable

Most of the work experience our team has accumulated is concentrated around design, supply, and installation of cable heating systems. Among the technologies that we use, the following stand out:

  • Self-regulating heating cable;
  • Resistive heating cable;
  • Skin-effected heating cable.

Self-regulating heating cable

Resistive heating cable

Self-regulating heating cable consists of 2 conducting cores parallel to each other. Between them, there is a polymer heating matrix, which is a polymer member capable of local alteration of its power depending on the ambient temperature: the power increases when temperature decreases, and vice versa. It does not blow when overlapped, and can be cut from spools into construction lengths at the place of installation. There are several various temperature modes, some of which heat up to 190 degrees, and withstand steaming temperature of 250 degrees maximum. There are variations of design with outer polytetrafluoroethylenum cover resistant to exposure to most aggressive environments. There is a range of maximum section length limitations. Starting currents surpassing rated currents by 2.5 times are a major factor.

Resistive heating cable consists of 3 conducting cores parallel to each other and made of copper-nichrome alloy that has fixed resistance per unit length. There is a vast resistance nomenclature from 0.8 Ohm/km to 8,000 Ohm/km that allows for selecting a required value for every specific task. Connection to the voltage of 380 V or 660 V. Connection type: star. Length of a single thread (one heating arm, from one connection point) is up to 1.5 km. 3-core performance allows for minimizing the possibility of local overlapping that causes its blowing.

It is very important that the cable heating technology itself can be more cost-efficient and convenient in the use compared to heat tracing, for instance.
