SFK Cable Carrier System Overview

The SFK cable carrier consists of a rectangular galvanized steel spiral band combined with an inner spring steel band. It provides large usable cross-sections with low external dimensions, offering optimal line protection. It is particularly suitable for environments with hot chips and sparks, and operates within a temperature range of -40 °C to +180 °C.

Ordering and Length Calculation

The order length (L) is calculated based on the maximum travel distance (Lv) and bending radius (R) using the formula: L = Lv / 2 + 4R. The straight length of the SFK is the order length minus a dimension 'z' (refer to the provided table for 'z' values).

Example order format: SFK 32N / 200 x 1900 / N/N, where the type, radius x length, and connectors/arrangement are specified.

Dimensions and Parameters

Flange Types and Connectors

• Flange N: Standard, economical flange with four mounting holes.
• Flange A: Modified flange N with countersunk screws, knurled nuts, and angles.
• Flange B: Laterally connected flange with angles; standard flange N holes are omitted.
• Scoop Mount: Additional connector type to enhance mounting options.

Arrangement Types

Three main arrangement types are described for connector placement:

• S1: 2 x outer radius
• S2: 1 x outer radius and 1 x inner radius
• S3: 2 x inner radius

Load and Carrying Length

The free carrying length (Lf) and load capacity (kg/m) depend on the specific SFK type, radius, and flange arrangement. Detailed load diagrams and specifications are referenced but not fully included in the excerpt.

Summary of Best Practices and Recommendations

• Calculate order length carefully using the provided formula to ensure proper fit and function.
• Select flange type based on mounting requirements and environmental conditions.
• Choose arrangement type (S1, S2, S3) according to installation space and load distribution needs.
• Consider the temperature range and environmental factors such as exposure to hot chips and sparks when selecting SFK type.

This document serves as a design guideline for ordering and specifying SFK cable carriers, providing critical dimensions, ordering examples, and connector options to optimize installation and performance.
