Power distribution

BTA: busbar trunking assembliesGuarantees a quality distribution system conforming to international standards IEC 61439-6.

When in place shows clearly the distribution circuit diagram and enhances the neatness and aesthetic of a decentralized distribution installation.

Designed in such way as to give the user a maximum of flexibility in use:

Modifications, additions and extensions can be carried out on the installation without disturbing normal activity.

By its simplicity, its rapid assembly and mounting, busbar trunking reduces on site labour charges.

Economical

It is economically profitable by comparison to a cabled installation after the 5th tap-off outlet.

Complete freedom of layout

At the design & installation stages of an electrical distribution system the layouts of the machine and workshop area are seldom finalised.

With tap-off outlets every 0.25 or 0.5 of 1 meter interval, busbar trunking gives the user the total freedom to : carry out tests, install, modify and remove machinery and equipment as required.

Adaptability to environmental conditions

An extensive range of tap-off boxes for automation control & distribution with contactors and circuit breakers can be adapted to difficult environments, dust & damp protection enclosures.

Complete safety

During installation and use, a number of special features have been incorporated into the design of the trunking that eliminate positively any possible errors due to :

I faulty erection, (which is impossible)I unfinished operationsI faulty operationsI easy and rapid jointing of trunking lengths simply by in experts

saving costly manpower.I tap-off outlets protected by automatic shutters a proven safety system for

total security.

Reactive power compensations & Industrial controls

Industrial ControlA complete range of Industrial control and automation equipment for :I electromechanical and electronic power switchingI protection and controlI data acquisitionI data processingI user/machine interfacingI supervision & controls using PLCs, supervision software and industrial interface terminals

I magnetic contactorsI control & protection relaysI all ranges of motor startersI soft starter & variable speed speed drivesI control & signaling devicesI limit switchesI proximity switchesI photo electric detectors.

Reactive power compensation SZC cylindrical capacitors are dry capacitors with a tubular casing covering a wide range of powers and voltages both in 50 Hz and 60 Hz.Its design, manufacturing and testing processes mean that SZC cylindrical capacitors have a high degree of quality and have an extremely long life.

ADEX has a series of electromagnetic filters for the elimination of harmonics named ‘Compensators’. These equipments are based on the cancellation and compensation of magnetic fluxesThe main advantage of the Compensator is the absence of electronic components and capacitors. The Compensators are therefore maintenance free, have an extremely long lifetime compared with other types of filters and are compatible with any electrical installation

Static regulators (real time)Regulating reactive energy using a static system is ideal for installations which are sensitive to transients or with very fast reactive power fluctuations (< 0.2 s).

Reactors for filteringCapacitor banks with rejection filters are designed for systems with a significant harmonic content. They avoid possible resonances with the system and capacitor overload. In order to do this they have a series of reactors and capacitors tuned to a frequency which does not coincide with any harmonic range.

WINDING

Low voltage windings are generally layer, helical or disc type. For high voltage windings, flat enamel conductors are used in layer or disc winding technique depending on the voltage and current.

The technologies used are copper or aluminium windings providing transformer its short-circuit strength in accordance with current standards.

Winding is the most important and sensitive part of transformer. Their design and construction decide transformer’s parameters demanded by customers.

This section consists series of fully computerized foil and other winding machines for HV,MV and LV coils for all types of conductors, strips and round wires.

Before being placed in the tank, the active part are dried up using vacuum drying oven for removal of moisture and other impurities.It is crucial requirement in transformer ensuring trouble free operation through the life span of the transformer.
