Here's a product description for the heat shrink tube:
Our 10kV PVC heat shrink tube provides superior electrical insulation and protection for low-voltage applications. Engineered with high-quality PVC material, this low-pressure tubing offers excellent resistance to moisture, chemicals, and abrasion while maintaining flexibility for easy installation. When exposed to heat, it shrinks uniformly to create a tight, professional seal around cables, wires, and connections. With a voltage rating of 10kV, it's ideal for electrical insulation, wire bundling, and mechanical protection across industrial, automotive, and telecommunications applications. The tube features a 2:1 shrink ratio and comes in various sizes to accommodate different wire gauges. This versatile heat shrink tubing provides long-lasting protection while meeting international safety standards, making it perfect for both indoor and outdoor installations where reliable insulation is crucial.
