PowerSyntax features

SPX - SPZ - SPY - SPV

Technical specifications, main features and applications of the PowerSyntax family of Powerlock-style single pole connectors.

SPX, SPZ, SPY and SPV are the new PowerSyntax series of Powerlock compatible single pole electrical connectors. Power Syntax are specifically suited for the electrical supply management from 480amp up to 750amp. Although fully intermateable with the original (and all the previous Syntax versions), the new PowerSyntax features a number of mechanical and technical enhancements which have been designed and incorporated to redefine the standards on this category of connectors as for safety, reliability, ease of handling and robustness in the harshest conditions.

Contact guide pin

For easy alignment of the holes on contact and insulating body, and quick insertion of the red dowel pin, the PowerSyntax contacts feature a guide pin with a corresponding recess in the insulator. With the guide pin automatically driving the contact in its correct position, the assembling operations are easier and quicker. Thanks to this solution, the contacts can be assembled even in harsh environmental situations.

After locating recess A in the body, find guide pin B on the contact, then insert guide pin B inside recess A, as shown in picture C. For contact fastening, after locating hole D on the body, insert dowel pin E in hole D. Contact retention is then completed as shown in picture F.

The external shell has an ergonomic design which grants optimal handling and grip, also when operating with gloves. In particular, the sides of the hand grip are specifically designed for easy pushing/pulling of the connector when mating/unmating.

Multilouver contact band and locking mechanism

The multilouver contact band is the core of this standard of connectors. However, on some legacy connectors, the way the contact band retention system is engineered does not ensure its positive locking. With the multilouver contact band out of its recess, the conductive surfaces will no longer be in contact, impeding the current transfer (1). To ensure the efficiency of the connection in any situation, we adopted a solution which keeps the multilouver spring loaded band in its positive location. The contact band is held in its locked position by a special ring, on which a 2.5 ton. pressure has been applied (2).This solution prevents derailment of the multilouver contact band (3).

Source contact IP2X threaded protection

On PowerSyntax, the touch-proof protection on source contacts features a threaded attachment for improved safety. Since this style of connectors were first introduced on the market, the typically harsh conditions of their everyday usage might result in breakage of the insulation caps, with risks for the operators’ safety as the edges of the metal conductive parts remained totally exposed. Thanks to this solution, the touch-proof cap is positively threaded and then blocked with specific adhesives to make it immovable. This system reduces the risk of breakage as the bond between the protective elements and the live parts is strengthened, while improving safety for the users through reduced exposure of the metal parts, as a portion of the insulating cap will remain in its position on top of the source contact even in case of damage.
