غطاء جلبة بزاوية قائمة/مضمنة قابل للانكماش الحراري

لا تعتمد جميع الكابلات في معدات الطاقة على أسلاك مستقيمة عند خروجها. ففي لوحات التوزيع والمحولات وغيرها من معدات توزيع الطاقة، قد يتم توصيل الكابلات من الجانب أو الأسفل أو بزوايا محددة. وفي حال استخدام أكمام الانكماش الحراري الأنبوبية المستقيمة العادية مباشرةً، قد تحدث مشاكل مثل عدم كفاية التغطية، أو الانكماش غير المتساوي، أو ضيق مساحة التركيب في المناطق الركنية.

استجابةً للمشاكل المذكورة أعلاه، تعتمد مجموعات أغطية البطانات الحرارية القابلة للانكماش من CCMT على بنية مُشكّلة مسبقًا، ويمكن اختيار نوع مستقيم أو بزاوية قائمة وفقًا لاتجاهات الخروج المختلفة. في الوقت نفسه، تُغطى الجدران الداخلية لكلا الطرفين بمادة لاصقة ذائبة بالحرارة، مما يُشكّل بنية مُحكمة الإغلاق بعد التسخين والانكماش. بالمقارنة مع المعالجة المُعقدة التي تُجرى في الموقع باستخدام أنابيب الانكماش الحراري العادية، يُمكن للغلاف المُشكّل تقليل التعديلات الهيكلية أثناء عملية التركيب وتحسين اتساق تركيب دفعات المنتجات المختلفة.

مقدمة عن المنتج:

غطاء الكابلات ذو الزاوية القائمة والقابل للانكماش الحراري مصنوع من مادة البولي أوليفين، وهو عبارة عن جزء عازل حراري مُشكّل مسبقًا وقابل للانكماش. يتوفر المنتج بتصميمين: زاوية قائمة ومستقيم. الجدران الداخلية لكلا الطرفين مطلية بمادة مانعة للتسرب بالذوبان الساخن. بعد التسخين، يمكن تثبيته بإحكام على الكابلات ومناطق توصيل المعدات. يُستخدم هذا الغطاء في أجزاء توصيل الكابلات في لوحات المفاتيح والمحولات وغيرها من معدات الطاقة، حيث يوفر عزلًا إضافيًا، وإحكامًا، وحماية من العوامل البيئية.

مواصفات المنتج:

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.

About CCMT:

CCMT was established in 1986 and has long focused on the research and development, production and supply of power and communication cable accessories. Its product system covers heat shrinkage, cold shrinkage, cable terminals, cable joints, sealing materials, waterproof materials and overhead line protection products. After 40 years of industry accumulation, the company continues to carry out research and development of polymer materials, heat shrinkage and cold shrinkage technology-related products, and has received support from technical resources such as Changchun Institute of Applied Chemistry.

Our own manufacturing system supports stable batch supply.

CCMT has a production base of approximately 10,000 square meters and a professional production team of more than 100 people, and is equipped with more than 40 sets of professional production equipment. Our company has 13 plastic extrusion production lines, 10 oil expansion production lines and 3 silicone rubber extrusion production lines, forming a complete manufacturing system from raw material processing, product forming to finished product testing, and providing a manufacturing foundation for OEMs and batch orders.

Bulk supply capabilities.

Different CCMT products have different production capabilities. For example, the monthly production capacity of heat shrink tubing/sleeve can reach approximately 5 million meters, the monthly production capacity of cable end caps is approximately 30,000 pieces, and the monthly production capacity of heat shrink and cold shrink cable terminals/joints is approximately 10,000 sets. The production capacity of specific products will be adjusted according to specifications, order quantity and production schedule. The purchaser can confirm the delivery date and supply capacity of the corresponding model during the inquiry stage.

ISO quality management and product testing.

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.
