Induced over-voltage from atmospheric origin and electromagnetic
disturbances destroy, each year, communications systems.
The line transformer and its use
An essential product, more topical than ever in view of the growing
development in the analog and digital transmission systems. This high
quality transformer is a passive component, simple, efficient, extremely
reliable and, moreover, not expensive.
The line transformer and its
function
A line transformer is essentially designed to:
|
match the line impedance to the one of the equipment
to protect, in order to avoid reflection losses |
|
transmit the voice currents, the high-frequency signals
or the remote-control pulses, in maintaining a composite weakening
level as low as possible in the transmitting voice band |
|
prevent with galvanic insulation the propagation of
induced over-voltage, undesirable on aerial and underground lines,
up to the equipment to protect |
|
artificially constitute zero voltage points for phantom
circuits |
|
transmit the ringing current with a high level of efficiency |
Protect
- Secure - To match
The line transformer is apart of the following equipments:
|
Protection & security for phone and communication
network of ISDN/ADSL customer |
|
Protection & security for ADSL connection, modems,
PC |
|
Protection & security for all telecommunication
equipment working in power line and electrical traction area |
|
Protection & security of mobile transmission (radio,
UMTS, GSM) for the terrestrial line protection |
|
Protection & security for data transmission lines
MIC, xDSL |
|
Protection & security for data transmission MIC,
xDSL by power lines |
|
Protection & security for audio transmission and
systems |
|
Match the line impedance to the one of the
equipment, in order to avoid reflection losses |
|
Transmit the ringing current with a high efficiency |
|
Protect & secure the measures instruments |

Manufacturing
standards
Our products' manufacturing standards meet the specifications of SWISSCOM
Ltd and CFF (Swiss railways). The first-rate performances of our products
as well as their extreme reliability are due to a great experience, the
selection of the highest quality materials, and to a particularly careful
manufacturing. Furthermore, each transformer undergoes a complete
quality control.
