Tyree 0B&S (50mm²) Single Core Marine Tinned Power Cable | MBS172803
Key Features & Benefits
-
Defensive Tinned Copper Shielding: Manufactured with a high-conductivity multi-strand Tinned Copper Wire (TCW) conductor compliant with AS/NZS 1125. The protective tin coating stops oxygen, salt air, and moisture creep completely, saving your electrical system from "black wire" or "green death" corrosion.
-
Massive 246A Current Capacity: Safely rated for a continuous 246 Amps (@ 30°C). This massive gauge ensures your power-hungry, high-end electronics operate at maximum capacity without bottlenecking your system or overheating the wiring.
-
High-Temperature Thermal Protection: Encased in heavy-duty, RoHS-compliant V90 PVC insulation rated to handle temperatures up to 90°C. It is highly resistant to flames, fuels, oils, and intense ambient engine bay or bilge heat.
-
Outstanding 708-Strand Flexibility: Despite being a massive 50mm² cable, the high-density composition of 708 individual strands makes it incredibly flexible. It is significantly easier to work with, pull through tight bulkheads, or snake along vehicle chassis rails than rigid standard wire.
