Tianhongxiang YC2*2.5 rubber-sheathed red copper wire, medium and low voltage power cable, outdoor insulated wire for bridge engineering

YC 2×2.5 Rubber-Sheathed Red Copper Wire (Special for Bridge Engineering)
This is a heavy-duty general-purpose rubber-sheathed flexible cable, specifically designed for outdoor, heavy-load, and mobile scenarios such as bridge engineering. Its core advantages include weather resistance, wear resistance, mechanical strength, and ease of installation.
I. Core Parameters (Tianhongxiang YC 2×2.5)
Model: YC 2×2.5 (Heavy-duty rubber-sheathed cable, 2 cores, 2.5mm² per core)
Rated Voltage: 450/750V (Medium and low voltage power transmission)
Conductor: 99.99% oxygen-free red copper (red copper), 5th class soft copper conductor, multi-strand stranded, extremely flexible
Insulation: Ethylene propylene rubber (EPR), excellent insulation performance, heat resistance, and aging resistance
Sheath: Heavy-duty rubber compound, wear-resistant, oil-resistant, acid and alkali resistant, UV resistant, and weather resistant
Operating Temperature: Long-term allowable temperature of the conductor ≤ 60℃; environmental application -35℃ to 60℃
Bending Radius: ≥ 6 times the cable’s outer diameter, suitable for the complex routing and frequent movement of bridges
Current Carrying Capacity Reference: 2.5mm² copper core, safe current carrying capacity at room temperature is approximately 16 to 20A
II. Core Selling Points (Suitable for Bridge Engineering)
Superior Mechanical Performance
Can withstand dragging, crushing, and bending during bridge construction and maintenance, with strong resistance to mechanical damage.
Outstanding Outdoor Weather Resistance
Resistant to sun exposure, rain, temperature differences, and salt spray, suitable for long-term use in open-air, high-altitude, and humid environments of bridges.
Oil and Dirt Resistance
Suitable for oil, dust, and chemical contact scenarios at bridge construction sites, with the sheath not easily aging or cracking.
High Flexibility
Multi-strand fine copper wire + rubber structure, facilitating wiring in complex spaces such as bridge box girders, piers, and supports, as well as temporary wiring.
Safe and Reliable
High insulation strength, passing a 2000V/5min withstand voltage test, ensuring stable medium and low voltage power supply.
III. Typical Applications in Bridge Engineering
Temporary power supply for bridge construction (welding machines, vibrators, lighting, mobile equipment)
Wiring for permanent bridge auxiliary facilities (lighting, monitoring, sensors, maintenance sockets)
Outdoor fixed/mobile power distribution for piers, box girders, bridge decks, ramps, etc.
Connection of mobile power sources for bridge maintenance and repair equipment
