The company SPM Special Machine is an Italian manufacturer rapidly gaining recognition worldwide for its innovative design and engineering of special electrical equipment intended for hazardous areas where flammable gases, vapours or explosive dusts may be present (such as petrochemical plants, refineries, mines, offshore platforms).
In this article, we will present some of the key products developed by SPM Special Machine, ranging from cable reels to slip rings, and finally the products specifically designed for mining applications, such as medium-voltage junction boxes and the ATEX motor-driven cable reel system.
Explosion-proof cable reels can be equipped with either spring-driven or motor-driven systems (electric, hydraulic, or pneumatic).
The cable drum is manufactured entirely from stainless steel and is designed to handle flexible power, control, or data cables.
A roller guide system or a cable distribution system ensures uniform winding and unwinding of the cable.The slip ring consists of low thermal-resistance sliding contacts housed inside a flameproof enclosure (certified Ex d, ATEX, IECEx).
The electric motor is a heavy-duty torque motor Ex d, which automatically manages all phases of cable winding and unwinding.
Another area of expertise for SPM Special Machine is spring-driven cable reels.With a construction entirely in AISI 316L stainless steel, these products are suitable for long travel distances and medium-power applications, and can be installed either vertically or horizontally.

In the figure, a power supply system with a conductor bar can be seen, where a motor-driven cable reel for hazardous areas is installed for medium-voltage tunnel applications.
The system supplies a tunnel boring machine (TBM) with an approximate power of 3 MW, using explosion-proof junction boxes with Ex db protection.The EX protection type of the system is Ex h – ATEX category I M2, and the same design can also be developed according to the IECEx scheme.
The special motor-driven cable reel consists of a painted steel drum, on which a robust, flexible medium-voltage cable (12/20 kV) is wound.
The drive system is powered by a motor-gearbox assembly and the cable winding and unwinding operations are controlled by a dedicated electrical control panel.
The core component of the motor cable reel is the slip ring, which is housed inside an Ex db flameproof enclosure.
This high-performance slip ring is designed for heavy-duty environments and is significantly more compact than competing products.Its uniqueness lies in the fact that the active parts are not air-insulated, but instead isolated through a multi-layer insulation system, enabling the slip ring to reliably withstand high voltages up to 24 kV and maximum currents of approximately 680 A.
This high-voltage slip ring with insulated active parts is a patented technology of SPM Special Machine, allowing the company to meet new challenges in markets requiring extreme engineering solutions..
