Drallim Industries Ltd

As the European Telecom industry increasingly standardizes upon ETSI standards, Drallim introduces a new, high-capacity waveguide dehydrator for location in both ETSI and standard 19" racks. Reversible mounting brackets allows the same unit to fit within either enclosure without any further need for mounting brackets or plates.

The 12447 Waveguide Dehydrator uses an efficient 1/3 HP compressor to fill its integral receiver ready for distribution. Another useful feature of this unit is the humidity detector test facility, which assists in fault analysis alongside the standard remote alarms. In common with all of our current units, the 12447 is equipped with a thermal/magnetic overload circuit breaker with neon indicator.

The DRALLIM Compressor Desiccator Unit 12450 (CDU 3C) is an energy saving integrated unit for supplying dry air to pressurised cables. It has been designed to alleviate the need for gas bottles in smaller exchanges, and the low dB rating allows the unit to be safely sited in manned areas. The CDU 3C consists of a small cabinet housing the compressor, desiccator, humidity detector and all electrical and pneumatic control circuits. An air receiver forms an integral part of the unit. The CDU 3C can be installed to be either wall or rack mounted using its alternative bracket positions, or can equally be sited as a floor standing unit if preferred.

The combination of a multipole electric switch with the Drallim valves heralds a new era in process safety systems. The introduction of an explosion category electric switch further enhances the applications to which these devices are applied.

Detection of acoustic partial discharge.

The ATTanalyser is a simple and effective stand-alone tool to aid in commissioning tests of gas-insulated switchgear (GIS) systems and power transformers. TheATTanalyser reduces delays in commissioning and maintenance by locating flaws in GIS systems and transformers acoustically.

The PFT Series of AC hipots are ideal for testing many types of substation apparatus, motors/generators, isophase bus, and other loads requiring an AC withstand test. The HV Inc AC hipots are among the smallest, lightest, and most economical available while delivering higher power ratings and features not found elsewhere.

A host of higher power AC Test Sets are available up to 40kVA for performing AC withstand testing on all types of electrical apparatus. Various control packages are available: simple manual controls, automated and computer compatible controls, and fully microprocessor based controls for complete test automation and data collection.

Drallim understands the great advantage to OEMs by having role equipment fixed provisions designed in with the airframe. This avoids costly modifications and supplementary type certificates becoming a burden its customers. Drallim works closely with the OEM airframe designer to offer Cargo Hook installations, mounting arrangements and attachment points.
