Cross Clamp L-65 (Round / Strip Conductor)
The Gromtor L-65 connects Ø8–10 mm round conductors with strip conductors up to 40 mm in cross and T-shapes. The 65 × 65 mm body is designed for wide strip cross-sections and high mechanical loads.
The L-65 is designed to work with wider strip cross-sections in round-to-strip transitions. This model is used in applications exceeding the L-55's 30 mm limit — up to 40 mm wide strip conductors.
As the strip cross-section increases, two things change. First is the current carrying capacity: wider strips are preferred in main earthing lines and structures requiring a high level of protection. Second is the mechanical load: a wider strip is more rigid, transferring more force to the connection point. The 65 × 65 mm body provides the necessary contact surface and bolt clearance to withstand this load.
In practice, selection is simple: the model is chosen according to the width of the strip. L-55 for up to 30 mm, L-65 for up to 40 mm. The round conductor side is Ø8–10 mm in both models.
The product is manufactured in accordance with IEC 62561 standard and meets IEC 62305 system requirements.
