Cable-to-cable exothermic welding molds are purpose-built graphite molds for joining stranded copper cables with a permanent molecular bond.

Unlike mechanical clamps, compression sleeves, or bolted joints, an exothermic cable-to-cable weld creates a low-resistance, corrosion-resistant connection that does not loosen under thermal cycling or fault current.

If you are sourcing exothermic welding molds Cable-to-Cable CC1, CC2, CC4, CC6, CC7, CC11, CC14, this category covers the standard connection styles.

Cable-to-Cable Connections

This range focuses on commonly requested Cable-to-Cable mold codes:

• CC1 / CC2 — compact cable-to-cable joints for lighter grounding conductors and smaller splices
• CC4 / CC6 / CC7 — mid-range connections for standard copper cable sizes in earthing grids and equipment bonding
• CC11 / CC14 — heavier cable sections and higher-capacity joints where weld volume and mold cavity size must match larger conductors

Exact mold selection depends on cable cross-section, number of conductors, and joint type. Share your conductor dimensions and connection sketch, and we will confirm the correct CC mold, welding powder charge, and handle/frame accessories.

Applications

CC cable-to-cable molds are widely specified for:

• Copper grounding grid and mesh cable splices
• Substation and earthing cable extensions
• Lightning protection down-conductor and equipotential bonding cable joints
• Industrial plant and rail grounding where compression or bolted splices are not preferred

Because the finished weld is permanent, these molds are preferred on projects that prioritize long-term electrical continuity and reduced maintenance.

Choose

To choose among CC1, CC2, CC4, CC6, CC7, CC11, and CC14, confirm:

1. Conductor size — cable mm² (or AWG) for each run
2. Joint orientation — straight splice, tee, parallel, or multi-cable layout
3. Powder size — matched weld metal volume for a complete fill

Using the wrong cavity size is the most common cause of incomplete welds. If your cable size sits between two codes, request a size chart before ordering.
