Drag chain, reeling, ROV and UAV tether constructions. Manufacturing in Shanghai since 2015. We design conductor, insulation, tensile and jacket layers around your duty cycle — not around a catalogue.
Six construction families covering the duty cycles that standard cable fails in.
High-flexibility cable for linear reciprocating motion inside a cable carrier. Tinned copper, PUR or PVC jacket, optional shielding.
For drum, reel and festoon systems, with tensile member and anti-torsion lay to resist winding stress.
Density held below 0.98 g/cm³ so cable weight does not disturb vehicle trim.
Lightweight hybrid power and optical construction for continuous flight.
Polyurethane jacket for abrasion, oil contact and low-temperature flexibility.
Flat profile for tight radii, compression resistance and robot dress packs.
Standard constructions are stocked as extrusion runs, so a 100 m order carries the same lead time as a larger one. Custom constructions are quoted individually because a new extrusion run and type test may be required.

In-house stranding, extrusion and testing — not a trading office.
Stranding pitch, insulation wall, tensile layer and jacket compound specified per duty cycle.
Stranding, extrusion and cabling under one roof, from 100 m pilot runs to volume orders.
Conductor resistance, insulation resistance, high-voltage withstand and dimensional checks per batch.
CE and RoHS declarations, test reports and packing lists issued with every shipment.
Flex life is set by the jacket compound, not by the cable family. Both are available on the same conductor construction.
| Jacket | Flex life | Temperature | Selected for |
|---|---|---|---|
| Nitrile (NBR) | 3,000,000+ cycles | -15 to +70 °C | General drag chain duty, oil contact |
| Polyurethane (PUR) | 5,000,000+ cycles | -40 to +80 °C | High cycle count, abrasion, low temperature |
For ROV, inspection-class vehicles and subsea tooling. Density below 0.98 g/cm³ keeps the cable near neutral in seawater; TPEE insulation and jacket resist hydrolysis and repeated flexing.
| Parameter | Value |
|---|---|
| Rated voltage | 300 / 500 V |
| Operating temperature | -40 to +80 °C |
| Density in water | < 0.98 g/cm³ |
| Min. bend radius, fixed / flexing | 8D / 10D |
| Conductor | Tinned copper |
| Insulation / jacket | TPEE |
| Tensile member | Aramid, per duty |
| Compliance | CE · RoHS |
Answering the points buyers raise before a first order.
The minimum order quantity is 100 metres, for both standard and custom constructions. There is no small-order penalty.
Standard constructions ship in 5-7 days ex-works Shanghai. Custom constructions are quoted with their own lead time, because a new extrusion run and type test may be required.
Yes. A CE declaration of conformity and RoHS test reports are issued with the shipment, together with inspection records and a packing list.
Drag chain cable is designed for linear reciprocating flexing inside a cable carrier and is optimised for bend life. Reeling cable is designed for winding onto a drum or reel, so it must also carry tensile load and resist torsion. Using one in the other's duty cycle is the most common cause of premature cable failure.
Neutral buoyancy cable is used on ROVs, inspection-class subsea vehicles and underwater tooling, where the weight of a standard cable would disturb vehicle trim. Density is held below 0.98 g/cm³ so the cable is close to neutrally buoyant in seawater. Rated 300/500 V, operating range -40 to +80 °C, minimum bend radius 8D fixed and 10D flexing.
Duty cycle (drag chain, reeling, static subsea or tether), travel length or minimum bend radius, rated voltage, core count and cross-section, operating environment including oil, salt water, UV and temperature, and any tensile or buoyancy requirement.
Flex life is governed by the jacket compound. Nitrile (NBR) is rated for 3,000,000+ flex cycles over -15 to +70 °C; polyurethane (PUR) for 5,000,000+ cycles over -40 to +80 °C, with higher abrasion and oil resistance. Both jackets can be applied to the same conductor construction, so the choice is a duty-cycle decision rather than a separate product.
Constructions are built to customer specification under our enterprise standard, which is what allows 100 m runs of a non-catalogue design. Where a project calls for IEC or EN referenced construction, it is quoted against that reference and the test schedule is agreed before production. CE and RoHS documentation is issued with the shipment either way.
