4x4 elevator pit TTR cable is a multi-core cable consisting of 4 conductors, each with a cross-section of 4 mm², designed for high power demand applications in elevator pits. In pit areas, where lighting systems, auxiliary power circuits, and energy-consuming equipment operate, selecting a cable with sufficient cross-section and current capacity is critically important.

The 4-core structure allows phase, neutral, ground, and an additional power or control line to be carried through a single cable in an organized manner. This structure simplifies the installation, reduces cable congestion, and helps maintenance personnel quickly identify lines during service and inspection operations in the elevator pit.

Thanks to its copper conductor structure, the cable provides low conductor resistance and offers an air current carrying capacity of 32 A according to the specified technical values. This capacity enables safe power supply for stronger lighting groups, auxiliary motors, or equipment operating under continuous load in the elevator pit. The low resistance value also contributes to reduced energy losses and stable system performance.

Its flexible structure facilitates installation in confined elevator pit areas despite its larger cross-section. Designed for vibration-prone operating environments, the cable minimizes mechanical stress that may occur during operation and ensures long-term durability. The robust outer sheath protects the cable against friction, impact, and mechanical stresses commonly encountered in elevator pit conditions.

From a technical planning perspective, the approximate outer cable diameter of 12.1 mm, weight of 277 kg/km, and 100-meter supply length support accurate cable routing and measurement planning before installation. These technical specifications contribute to safe and controlled installation and maintenance processes.

4x4 elevator pit TTR cable is preferred in elevator pit applications requiring higher power capacity, providing reliable energy transmission and a well-organized electrical installation.
