High-power DC charging brings heavy cables, and heavy cables are one of the most common practical complaints on a busy charging site. This 240 kW dual-gun installation at China shows how an overhead cable retractor system changes the daily experience for both drivers and site operators.
The Site at a Glance
- Site type: China — outdoor commercial car park with open parking bays
- Installed equipment: 240 kW dual-gun DC fast charging stations with overhead cable retractors
- Configuration: two charging guns per cabinet, able to charge two vehicles at the same time
- Platform range: the same station platform is available across a 240 / 320 / 360 / 400 kW series
What the Installation Looks Like
1. A row of dual-gun stations on an open car park
The installation runs as a line of identical floor-standing cabinets along the parking bays — a layout that makes it easy for drivers to find a free connector and for technicians to service the units from one side. Each cabinet uses a two-tone enclosure with a dark grey frame and white side panels, with louvered vents for internal cooling.
2. Two vehicles charging from a single cabinet
The dual-gun design is what makes the layout efficient: one cabinet serves two parking bays, so the same footprint and the same grid connection cover two cars at once. In the photo below, both guns are in use simultaneously. Cable tension arms with coil springs lift the heavy charging hoses off the ground, and the sections closest to the vehicles are wrapped in protective sleeving to reduce wear at the point where the cable bends most.
3. Status, interface and cable protection
Each cabinet carries a central display with QR codes on either side for app-based charging, a status indicator above the screen, and vertical LED light strips that keep the unit visible after dark. The charging gun sits in an illuminated holster on the side of the cabinet, so drivers can find the connector immediately, and the hoses are protected by ribbed spiral sleeving along the sections that see the most abrasion.
4. Cable retraction at scale
On a larger site, the retractor system is what keeps a multi-bay installation tidy. Instead of thick DC cables lying across the parking surface, each hose is suspended from an overhead pulley and tension line, and the gun holster ring stays lit so the bay reads clearly from a distance.
Product Highlights
- 240 kW dual-gun output — one cabinet, two guns, two vehicles charging at the same time.
- Overhead cable retractor system — tension-balanced suspension keeps heavy DC cables off the ground, so the site stays clean and drivers do not have to lift the full cable weight.
- Integrated cable protection — tension arms with coil springs, ribbed spiral sleeving and protective wraps on the most abraded sections.
- Clear user interface — central display with dual QR codes, a status indicator above the screen, and vertical LED light strips for visibility at night.
- Illuminated gun holster — drivers can locate and dock the connector quickly, which shortens each charging session.
- Serviceable cabinet design — two-tone floor-standing enclosure with side louver vents and a single-side service layout.
- Series flexibility — the same platform is offered across a 240 / 320 / 360 / 400 kW range, so one product family can cover different site requirements.
Why Cable Retraction Matters at This Power Level
At 240 kW and above, the DC cable is genuinely heavy, and how it is handled decides whether a site feels well run. An overhead retractor keeps the hose clear of standing water and out of the driving lane, reduces drag and abrasion on the cable, and lets a driver plug in without wrestling the full weight of the lead. It also protects the connector over thousands of cycles — which is exactly the part of a high-power installation that is most expensive to replace.
