Equipotential Bonding for Trusses – Padura’s Safety Solution for Event Technology

Why Equipotential Bonding for Trusses Is Indispensable

Trusses are electrically conductive—and without proper equipotential bonding, they pose significant hazards. Fault currents, voltage surges, or lightning strikes can generate life-threatening voltage differentials. Equipotential bonding ensures that all conductive parts maintain the same electrical potential—an absolute must for safe, standards-compliant event installations.

Padura Product Innovation: Connection Pin with Built-in Equipotential Bonding

Our subsidiary, Padura Elektronik, has developed a system to ground trusses in accordance with DIN 15700. The core component is a connection pin with an integrated bonding terminal, combining the mechanical fastening of trusses with the protective earth conductor—even effective on anodized, powder-coated, or painted surfaces where conventional clamps fail.

Key Technical Features:

• Robust construction made of electro‑galvanized steel alloy

• Mounting area with threaded hole for direct attachment of a cable lug

• Compatible with protective conductors per DIN 15750 (e.g., 16 mm² or 25 mm²)

• Integrated protective collar to prevent mechanical damage

• Drilled hole for spring cotter pin to ensure secure locking

• Permanent bonded installation—eliminates the need for repeated clamping/unclamping

• Compatible with standard cone connector systems used in event technology

• Provides reliable equipotential bonding even on coated trusses

Practical & Standards‑Compliant: For Safe Events of All Sizes

Whether for stage setups, exhibition construction, or temporary outdoor installations, the Padura connection pin integrates seamlessly into existing systems. Grounding is performed according to standards and without extra mounting steps—ideal for tight event timelines.

Event technicians, AV specialists, and lighting & sound firms benefit from simple handling, broad compatibility, and a robust safety standard that engenders trust with organizers and testing authorities.

Accessories for a Complete Equipotential Bonding System

In addition to the connection pin, Padura offers matching PE grounding cables designed specifically for modular truss systems:

• PE Ground Cable 0.5 m – for direct connection to the connection pin

  • Cable type: H07 RN‑F 1G16, black

  • Length: 0.5 m

  • Terminations: one side with DIN‑15700 standard plug, the other with ring cable lug for pin or grounding point

  • Use: connects truss to central grounding point

• PE Ground Cable with CONNEX cPOT Plugs – for modular connections

  • Cable type: H07 RN‑F 1G16, black

  • Lengths: 5 m, 10 m, 20 m

  • Terminations: DIN‑15700 standard plugs on both ends

  • Use: for linking multiple trusses or continuing the grounding path
