The isolating transformers are specifically designed to meet the main requirements of the TLC plant operators, that is to ensure continuity of operation to transmitter plants usually installed in remote areas, exposed to atmospheric discharges and connected to electric lines subject to important voltage drops. All the models are characterized by a low output impedance and are unaffected by load power factor. To ensure an excellent galvanic insulation and high common mode attenuation, the transformers are equipped with electrostatic shield and recessed concentric windings.
The range consists of single-phase and three-phase models up to 120 kVA.
Upon request, it is possible to produce customized versions with different electrical and mechanical characteristics.
Some models are fitted with surge protection. Class II models are also available.
Integrated power supplies AI series
The power supply of telephone plants and FM/TV relay stations has always entailed numerous problems and specific needs which are difficult to meet, among them:
– to assure the safety of operators working on the plants, according to the law;
– to assure continuity of operation to the plants;
– to build a compact distribution system for all loads usually present in relay stations;
– to limit the costs of installation and management;
– to allow a cheap and effective technical assistance.
The integrated power supplies AI, embodying safety, protection, distribution, connection and signal devices, satisfy all the above mentioned needs.
Isolating transformers IT series
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 to the difficulty of reaching the installation sites for carrying out maintenance, 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 plant protection and the operators safety. Since the isolating transformer is one of the most important components of the electric plant, the use of a specific product is essential.
These models share the ability of satisfy different and specific needs in the telecommunication field. Each series shows peculiar technical features designed for different kinds of TLC systems. Isolating transformers with different mechanical and electrical features can be manufactured on customer’s request.
All models are characterized by recessed concentric winding configuration, low output impedance and insensitiveness to load power factor, in order to assure high attenuation and good galvanic separation of the loads from the line.
