Internal Dividers: Temperature Range -20°C to 105°C

Component Specifications

Definition

Internal dividers are modular components installed within wiring ducts or cable management systems to create separate compartments for routing and organizing electrical wires, cables, or conductors. They prevent cross-contact, reduce electromagnetic interference, and maintain proper spacing as per electrical standards.

Working Principle

Internal dividers function by physically partitioning the interior space of a wiring duct into multiple channels. This segregation ensures that wires of different voltages, signal types, or circuits remain isolated, reducing the risk of short circuits, signal degradation, and overheating. They often feature snap-fit or slide-in designs for easy installation and reconfiguration.

Materials

Typically made from flame-retardant, self-extinguishing thermoplastics such as PVC (UL94 V-0 rated), polycarbonate, or ABS. Some industrial applications may use metal dividers (e.g., aluminum or steel) for enhanced durability or EMI shielding.
