HSCT Heat Shrink Butt Connectors 1. Product Description HSCT heat shrink butt connectors (commonly known as waterproof splice connectors) adopt a high-performance material combination: the outer layer is a composite of polyolefin and PA hot-melt adhesive, delivering strong insulation, reliable waterproofing, and anti-corrosion performance; the inner core is a high-purity red copper tube, ensuring excellent and stable electrical conductivity. Compared with conventional connectors, this product has better durability, and features easy installation and low installation costs. This image presents the connectors in their unused state. You can clearly see the color-coded (red, blue, yellow) outer tubing, and the high-purity red copper tube inside the tubing is also visible—helping you intuitively understand the product’s material composition and color-based specification distinction. 2.
