Pendant Control Cable with Twin Steel Support Elements

This pendant control cable family provides 300/500 V control connections with two steel support elements running along opposite sides of the cable. The 2ST construction uses extra-fine Class 6 copper conductors and PVC insulation; the R-type construction uses Class 5 copper conductors and XLPE insulation inside a twin-lobed PVC sheath.

Select the construction before selecting the circuit count. The support elements transfer suspended tensile forces to the designated clamps, while the insulated conductors carry the control circuits. This changes the suspension and termination design compared with an ordinary round control cable. Clamp dimensions must accommodate the support-member spacing or the complete twin-lobed profile.

The 2ST range covers 8G1.5, 12G1.5 and 20G1.5 configurations for movable panels and self-supporting shaft connections in high-rack equipment. R-type options cover 5 to 30 conductors of 1.5 mm² for overhead-crane pendant stations. Its documented suspended length is up to 50 m; use its own mechanical data when planning that route.

Specify the series, circuit schedule, suspended length, pendant mass and suspension arrangement with the enquiry. Check the flexible bending radius at the transition into the console and along any moving route. The configuration tables retain the different profiles and weights so the gland, clamp and available clearance can be matched to the selected cable.

Explore the port and festoon cable range for related configurations.

For self-supporting festoon and single-central-messenger crane control cables, compare these specifications: KYFLTFCY 300/500 V EMC Flat Festoon Cable with Suspension Element (for 300/500 V EMC-screened flat festoon installations with an integrated suspension strand); YSLTOE-J 300/500V Basket Control Cable (for round 300/500 V control drops supported by a central synthetic or steel strain-relief core). Check external support wire breaking load, core count, and pendant clamp compatibility before ordering.

Construction

The representative 2ST 8G1.5 illustration shows eight insulated copper cores, including one green/yellow protective conductor, inside a black PVC cable body. Two separate steel support strands occupy opposite lateral extensions of the sheath. R-type uses the different XLPE-insulated, twin-lobed construction listed below.

Applications

Use the twin steel supports with purpose-designed anchoring hardware to carry the suspended mechanical load at a pendant station, movable console or permitted shaft connection.

• 2ST: movable control panels, suspended control consoles and self-supporting shaft connections in high-rack systems; outdoor use within the stated operating conditions.
• R-type: remote-control push-button stations for overhead cranes, with a maximum suspended cable length of 50 m.
• Connect the steel support members to the designated strain-relief points so the electrical terminals do not carry the suspended mechanical load.
• Keep the series-specific bending radius at the pendant entry and moving transition. Include the complete cable profile when selecting clamps and glands.
• 2ST is not suitable for lift applications. Use a cable selected for the actual lift duty when that is the installation requirement.

When designing overhead hoist pendant stations and travelling crane festoon loops, review these resources: Crane Cable Manufacturer (for engineering support across crane festoon, reeling, basket, and pendant cable families); RONDOFLEX & PLANOFLEX Crane Festoon & Travelling Cable Series (0.6/1 kV) (for 0.6/1 kV round and flat rubber festoon cables on heavy gantry and bridge cranes). Confirm suspension height, oil and weather exposure, and numbered core layout.

Specifications

G denotes a configuration containing a green/yellow protective conductor; the stated total core count includes that conductor. R-type rows marked × do not add a protective conductor to the listed count.

2ST cable-body diameter and support-wire centre distance are separate dimensions. R-type dimensions describe the complete width × height profile.

The 2ST support value is tensile strength per steel element. The R-type value is the specified maximum load for both supports together; use the correct series value in the suspension design.

D is the cable diameter used for the selected construction. Maintain the specified moving bend radius throughout the suspended transition.

Dimensions and masses are nominal selection data. Include suspension hardware, hanging length and pendant load with the required configuration.
