1. Product Description
Trailer Cable Spiral Coiled Cable is a retractable power and signal transmission cable designed for trailers, RVs and commercial vehicles. Its unique spiral structure allows the cable to freely expand and contract between 1 meter (retracted state) and 3 meters (stretched state) while maintaining stable power and signal transmission. This cable is suitable for 12V/24V vehicle systems, integrating power supply, lighting control (turn signals, brake lights, reverse lights, etc.) and grounding functions, and is an ideal solution for connecting tractors and trailers.

2. Core advantages
Intelligent telescopic design
1:3 telescopic ratio (1m contraction/3m extension), automatic rebound, avoid entanglement
Patented spiral structure to ensure long-term durability

High load and stable transmission
7-core independent conductors: 5.26mm2 10AWG x2C+3.31mm2 12AWG x1C+2.08mm2 14AWG x4C
Support 25A high current (power line) and 5A signal current

Full environmental protection
IP67 waterproof and dustproof (can be immersed for a short time)
Cold and high temperature resistance (-40ºC~+105ºC)
Anti-oil & UV (no aging for long-term outdoor use)

Standardized interface
7-pin male and female connectors, plug and play
Color coding + digital numbering, anti-wrong insertion design

Super durability
Passed 50,000 telescopic cycle test

3. Typical application scenarios

Freight logistics
Power/lighting system connection between trucks and trailers
Brake lights & turn signal transmission of container trailers

RV travel
Power & lighting control of tractors and RVs
Power supply for external devices in campers

Engineering & agricultural vehicles
Lighting and hydraulic control of excavators/tractor trailers

Power transmission of agricultural equipment (such as planters and harvesters)

1. Safety use guide
Installation requirements
Make sure the vehicle is turned off before plugging and unplugging the cable
Check the corresponding function of each pin (avoid wrong connection)

Operation taboos
It is forbidden to operate at full load in a fully retracted state
Avoid the cable from contacting high-temperature parts such as the exhaust pipe

Maintenance recommendations
Clean the connector monthly
Test the line conductivity & insulation resistance quarterly

2. FAQ
Q1: Can it be used for electric or hybrid vehicles?
Yes, but ensure that the voltage matches (12V/24V) and avoid interference from the high-voltage system.

Q2: What should I do if the connector is flooded?
Immediately turn off the power and blow it dry with compressed air (hot air baking is prohibited). IP67 protection can be waterproof for a short time, but it needs to be replaced if it is immersed for a long time.

Q3: Maximum number of bends allowed?

Standard version ≥50,000 times of extension and retraction.

Q4: Can the signal cable transmit data (such as camera signals)?

Only analog signals (lighting control) are supported. If data transmission is required, the shielded enhanced version must be selected.

3. Summary
Trailer Cable Spiral Coiled Cable is a high-reliability solution for connecting trailers, RVs and commercial vehicles. Its intelligent retractable design, high current carrying capacity and full environmental protection performance make it the first choice in logistics, engineering and outdoor travel.
