ISOLATING TRANSFORMERS FOR TLC PLANTS

I R E M i a s l e a d i n g c o m p a ny i n t h e m a n u f a c t u re o f
electromechanical and electronic equipment for the control of
the mains power in the following sectors:
- powering of discharge lamps for professional applications;
- protection of electric users against line disturbances;
- luminous flux regulation in lighting plants;
- power generation by micro hydroelectric plants.
Since its foundation in 1947, IREM has gained wide recognition
due to the reliability and innovative content of its higt-tech
products. A reliable company deserving the Oscar-Award. In
1992, in Los Angeles, Mario Celso - founder of IREM - was granted
the “Scientific-Technical Award” by the Academy of Motion
Picture Arts and Sciences.
Two production plants, a philosophy based on “quality upgranding”
as the company’s primary concern and direct export exceeding
50% of the global turnover are a warranty of continuity and
development.
Experience, quality and professional skill: these are the factors
that permitted IREM to achieve in 1993 the certification of its
quality system in compliance with UNI EN ISO 9001 standard,
a further confirmation of IREM commitment to constant
improvement to ensure the maximum satisfaction of the customer
and its capacity to guarantee:
• a constant quality standard
• precision and repeatability of all working processes
• dropping of acceptance control at the customer’s plant
• identification and traceability of a product through the years.
In year 2000, IREM obtained the certification of its environment
management system according to UNI EN ISO 14001 standard.
This certification is a firm demonstration of the company’s will
to protect the environment not just through its products, but
also via precise patterns of behaviour.

The power supply of telecommunication plants and FM/TV relay
stations has always entailed numerous problems and specific
needs which are difficult to meet. We refer in particular to the
difficulty of reaching the installation sites for carrying out the
technical service, to the exposure to atmospheric discharges and
to the length of electric lines with consequent voltage drops.
The operators of TLC plants are well aware of the direct and
indirect costs deriving from a bad power supply. As a matter of
fact, the costs deriving from service interruption and from “low
audience efficiency” must be added to the failures which may
occur to the plants.
In order to obtain the maximum economic yield from the service, it is fundamental to build an electric plant assuring a good
protection of the transmission plants and the safety of
operators employed in plant maintenance. Since the isolating
transformer is one of the most important components of the
electric plant, the use of a specific product is essential.
The models included in this catalogue share the ability to satisfy
different specific needs in the telecommunication field. Each series shows peculiar technical features designed for different kinds
of TLC systems.
The following models are only a small part of what has been designed and manufactured up to now for satisfying the
specific needs of some of the most prestigious manufacturers of TLC plants in Italy and abroad.
Isolating transformers with different
mechanical and electrical features can be
manufactured on customer’s request.
All models are characterized by a recessed concentric winding configuration, a low output impedance and the
insensitiveness to load power factor, in
order to assure high attenuation and good
galvanic separation of the loads from the
line.
