The SAVER Group is equipped with the best modern machines and technologies for the different product lines.

In particular for filament wound tubes is able to satisfy standard requests from internal diameter 6 mm through 1000 mm and lengths up to 8.000 mm in an solid piece.
However, also solutions exceeding above mentioned dimensions (for example length higher than 8.000 mm) can be achieved with a customized approach with each single customer.

Main production equipment of SAVER S.p.A. is here below listed:

  • Multi-mandrel winding machines
  • Around 35.000 mandrels in order to cover as many diameters as possible
  • Several resin systems preparation equipment and vacuum impregnations systems
  • Several ovens for polymerization of composite materials
  • Several sandblasting machines and bonding systems
  • Extractors
  • Automatic machines and cutting systems
  • Several parallel and CNC lathes
  • Nr 6 clamping machines for silicon injection, including the biggest clamping machine in UE for liquid silicon injection
  • Several moulds for silicon sheds profile for composite insulators (cylindrical, conical, tapered)
  • Varnishing robots and chambers

Main production equipment of SAVER Alumen S.r.l. are referred to production of aluminium castings:

  • Ovens (gas powered)
  • Ovens (electricity powered)
  • Die gravity castings machines
  • Cutting machines
  • Machining equipment
  • Sandblasting machines
  • Thermal Treatment systems

SAVER Alumen S.r.l is equipped with different tools to control the aluminium casting process (temperature, density etc.…) and quality of the castings (X-rays machines). In addition, the company is equipped with laboratory control tools (mass spectrometers, tensile test machines etc.…) in order to control the quality of the alloy and of the castings.


The most important testing and control equipment of SAVER S.p.A. is here below indicated:

Equipment for mechanical testing:

  • Bending test equipment
  • Pressure and tightness test equipment with Helium gas and mass spectrometer device
  • Tensile and compressive test machines
  • Universal mechanical testing machine with indication of loads on digital display
  • Explosion resistant chamber for porcelain bushings pressure tests
  • Dilo system for vacuum and SF6 treatments
  • Tightness measuring systems by WIKA
  • etc.…

Equipment for electrical testing:

  • High Voltage Test Laboratory AC 750 kV for Partial Discharges detection with background noise 0,2-0,4 pC constantly calibrated and audited by the main OEMs and Utilities
