1. Heatshrink bushing boot kits are in right-angle and straight-through designs to provide protection for different cable outgoing directions.
2. The inner walls of both ends of the heat shrinkable right angle boot are coated with hot melt sealant, which fits the cable and equipment connection areas after heating and shrinking.
3. The straight boot heat shrink cable right angle is made of polyolefin material, which has trace resistance, ultraviolet resistance, insulation and thermal stability properties.
Not all cables in power equipment adopt straight outgoing wires. In switchboards, transformers and other power distribution equipment, cables may be connected from the side, bottom, or specific angles. If ordinary straight-tube heat shrink sleeves are used directly, problems such as insufficient coverage, uneven shrinkage, or limited installation space may occur in the corner areas.
In response to the above problems, CCMT's heatshrink bushing boot kits adopt a preformed structure, and a straight-through type or right-angle type product can be selected according to different outgoing directions. At the same time, the inner walls of both ends are coated with hot melt adhesive, which forms a closer fitting and sealing structure after heating and shrinking. Compared with the complex processing performed on site through ordinary heat shrink tubing, the molded sheath can reduce structural adjustments during the installation process and improve the consistency of installation of different batches of products.
Product Introduction:
The straight boot heat shrink cable right angle is made of polyolefin material and is a preformed heat shrinkable insulation protection part. The product is available in right-angle and straight-through structures. The inner walls of both ends are coated with hot melt sealant. After heating, it can be closely attached to the cable and equipment connection areas. It is used in cable connection parts in switchgear, transformers and other power equipment, providing additional insulation, sealing and environmental protection.

During actual type selection, it is recommended to simultaneously confirm the outer diameter of the cable, equipment interface size, outgoing direction and the size range of the sheath after shrinkage. The model cannot be selected based on the product name alone.
Product Advantages:
1. Pre-formed structure to adapt to different cable outgoing directions.
Right-angle and straight-through structures correspond to different equipment connection forms respectively. For equipment with lateral, bottom or right-angle outgoing lines, the corresponding structure can be directly selected to reduce the problem that ordinary heat shrink tubing needs to be cut, adjusted or repeatedly heated in the corner area. And pre-formed structures are also more suitable for standardized assembly and mass production.
2. Hot melt adhesive design at both ends strengthens the sealing of the connection area.
The inner walls at both ends of the heat shrinkable right angle boot are pre-coated with hot melt sealant. During the heating process, the sheath shrinks, and the hot melt adhesive softens simultaneously and adheres to the connection surface, filling part of the gap between the cable and the equipment interface. This structure not only provides insulation protection, but also further strengthens the blocking ability of the connection area to external factors such as moisture and dust.
3. Polyolefin materials combine electrical insulation and environmental protection.
Anti-track heatshrinkable bushing boots are made of polyolefin materials with volume resistivity ≥1×10 ‰ Ω·cm, dielectric strength ≥25 kV/mm, and have trace resistance and ultraviolet resistance. For power equipment connection areas that require long-term insulation protection, the purchaser can further confirm the applicable specifications based on the actual voltage level, installation environment and equipment structure.
4. Shrink range 2:1 - 3:1 for easy specification matching.
The cable size and connection interfaces of different equipment are not completely consistent. Anti-track heatshrinkable bushing boots have shrinkage ratios between 2:1 and 3:1 and thus compensate for changes in size across sizes. CCMT also supports customization of color, size and product specifications, and can match products according to the equipment manufacturer's structural size and batch purchase requirements.
Product Usage Scenarios:
· Cable outgoing for switch cabinets and distribution equipment
It is suitable for cable connection, lateral outgoing and bottom outgoing areas inside the switchgear, especially suitable for structures with compact equipment space.
· Transformer and equipment connection area
It can be used in cable connection parts in transformers and related power equipment to provide insulation and sealing protection for exposed or connection areas that require additional protection.
· Mass manufacturing of power equipment
For switchgear manufacturers, transformer companies, power system integrators and cable accessory dealers, right-angle or straight-through products can be configured according to different equipment structures to facilitate bulk procurement and standardized installation.

FAQ:
1. Can right-angle and straight-through sheaths replace each other?
Direct substitution is not recommended. If equipment space is limited or cables have obvious corners, using mismatched products may affect the fit and coverage after installation.
2. Does the internal hot melt glue cover the entire sheath?
Hot melt sealant is mainly coated on the inner walls of both ends of the sheath. This design focuses on strengthening the sealing protection of the interface area between the cable and the equipment, and avoiding the impact of completely filling the inside of the entire sheath with glue layer on the installation and shrinkage process.
3. Can it be disassembled or reused after shrinking?
Right angle heat shrink boots are a one-time installation product and are not recommended for disassembly or reuse.
