The STEFFEN TT installation cable is a 3-conductor fixed-wiring cable with 2.5 mm² cross-section, designed for permanent electrical installations in buildings. It provides reliable power distribution for standard household and commercial circuits.
3 conductors with 2.5 mm² cross-section handle standard load currents for lighting and socket circuits
25 m length covers typical room runs without the need for intermediate junctions
PVC insulation and sheathing provide durable protection against moisture and mechanical abrasion
White colour allows for clear identification and neat routing in conduit systems
What makes the STEFFEN TT cable stand out
As a dedicated installation cable rather than a flexible cord, the TT type is built for permanent routing through walls, conduits, and trunking. The 2.5 mm² conductor size is the standard choice for general-purpose indoor circuits, balancing current capacity with manageable cable diameter.
Ideal for...
Electricians and installers working on new-build or renovation projects in residential and commercial buildings. The cable suits standard lighting circuits, general-purpose socket outlets, and other fixed electrical installations where a 3-conductor configuration is required.

Route the cable through conduit, trunking, or directly in plaster as required by the installation method
