Accessories - Cable Clamps
Cable Clamps are included in the standard configuration unless specified in the purchase order.
Compatible with various charging cable diameters from 26mm to 43mm (to be specified during order confirmation).
Installation Requirements
The mounting area of the charging station should be structurally reinforced to prevent deformation under operational load.
Recommended reinforcement methods:
- Sheet metal thickness ≥ 5 mm
Mounting interface:
- 4 × Ø6 mm through-holes (for M6 fasteners)
Note：The rotational spring balancer is designed for operation without routine greasing under normal operating conditions.
Proven Application Use Cases
Retrofit Excellence: Bringing Order to Existing EV Infrastructure
Most discussions around EV cable management focus on the future – new stations where everything is integrated from day one. But what about the thousands of stations already in the ground?
Too often, existing sites are left with tangled cables and safety hazards due to perceived costs or installation complexity. At BESSUN, we’re changing that narrative. As specialists in EV charger cable management system, we know that retrofitting isn’t just a possibility—it’s a necessity for safety, site longevity, and a premium user experience.
See how we have transformed existing charging sations below.
Optimize Your Charging Station with the Correct Cable Management System
Choosing the right EV charger cable management system is essential for the longevity, safety, and user-friendliness of your DC charging stations. To ensure we provide the best possible solution, we require the following information:
- Cable Length
- Cable Diameter
- Total Cable Weight
By providing these details, we can conduct a thorough evaluation and recommend a system that meets your specific requirements, enhancing the efficiency and durability of your charging infrastructure.

FAQ
Is there a right version and left version?
There is no left or right version. The spring tube becomes rotatable after loosening screws, then it can be the same direction.
What is the difference between basic type and extended type?
The difference between the basic type and the extended type is the length.
What is your MOQ?
No MOQ. The sample lead time is 10 ~ 12 days.
What information should I provide when sending an inquiry?
To ensure we provide the best possible solution, it would be great to receive the following information:
- Cable Length
- Cable Diameter
- Total Cable Weight
Do all versions use the same spring?
No, the springs are not identical across all versions. Each model is equipped with a specific spring suitable to its load capacity and operational requirements.
How should I select a model if my specific weight or length exceeds the standard specifications in the table? (e.g., Diameter: 32mm, Length: 7m, Weight: 17kg)
If your requirements fall between two models, we strongly recommend selecting the next higher capacity model.
Example: For a diameter of 32mm, length of 7m, and weight of 17kg, you should choose the BSM-SB-1100-D34-37 rather than the BSM-SB-1100-D30-33.
Selecting a model with a slightly higher specification ensures safer operation and longer service life for the spring mechanism.
Can I use my own cable clamps with this cable managment system?
Unfortunately, no. Due to the unique design of this system, third-party cable clamps are unlikely to be compatible.
Do the DC charger’s panels require structural reinforcement to support the cable magement system?
Yes. The mounting area must be structurally reinforced to prevent deformation under the weight of the CMS. We recommend using a mounting surface with a sheet metal thickness of at least 5 mm to ensure adequate stability.
