As a dedicated manufacturer with over a decade of expertise, Jinhua Dika Electrical Equipment Co., Ltd. specializes in providing reliable electrical protection solutions. Our Flame-Retardant Heat-Shrinkable Sleeves are engineered to deliver superior insulation and safety for electrical busbars, a critical component in power distribution systems. With an annual export value reflecting our global reach and a commitment to quality underscored by our ISO9001 certification, we offer products that meet the stringent demands of international markets from North America to Southeast Asia.
These sleeves are designed to address the core challenges in electrical installations: preventing short circuits, mitigating fire risks, and ensuring long-term durability. By choosing our heat-shrinkable sleeves, you are investing in a product that enhances the safety profile of your electrical assemblies while simplifying the installation process.
Key Features and Technical Advantages:
- Enhanced Fire Safety: Manufactured from a specially formulated flame-retardant polyolefin material that meets recognized industry standards for vertical wire flame tests, significantly reducing the spread of flame in case of an electrical fault.
- Superior Insulation & Environmental Sealing: Upon application of heat, the sleeve shrinks tightly to form a seamless, conformal barrier. This provides excellent electrical insulation, high dielectric strength, and protection against moisture, dust, chemicals, and mechanical abrasion.
- Durable and Stable Performance: Designed to operate reliably across a wide temperature range from -55°C to +135°C, ensuring performance stability in diverse climatic conditions without cracking or becoming brittle.
- Easy and Fast Installation: The heat-shrink process is quick and requires minimal tools—typically just a heat gun. This translates to reduced labor time and costs on the production line or in the field.
- Customization and Versatility: Available in standard colors for phase identification (Black, Red, Yellow, Green, Blue) and can be produced in custom colors, lengths, and printed markings upon request to suit specific project requirements.
- Excellent Mechanical Protection: The shrunk sleeve provides a tough, abrasion-resistant layer that protects busbars from physical damage during handling, vibration, and operational life.

Frequently Asked Questions (FAQ)
-
Q: What is the primary purpose of this heat-shrink sleeve?
A: Its primary purpose is to provide electrical insulation, mechanical protection, and flame-retardant containment for copper or aluminum busbars used in switchgear, panel boards, and power distribution units. -
Q: How do I select the correct sleeve size for my busbar?
A: Choose a sleeve with a pre-shrink inner diameter slightly larger than the widest part of your busbar (including any connectors). The standard shrink ratio (2:1 or 3:1) will then allow it to conform tightly. We provide sizing guides and can assist with custom sizes. -
Q: What tools are needed for installation?
A: Installation typically requires only a standard industrial heat gun. The sleeve is placed over the busbar, and uniform heat is applied until it shrinks tightly and smoothly around the substrate. -
Q: Are these sleeves suitable for outdoor applications?
A: Yes. The material offers good resistance to UV radiation, moisture, and a wide operating temperature range, making it suitable for both indoor and outdoor enclosures, though specific environmental factors should be considered. -
Q: Can I get sleeves in colors other than black?
A: Absolutely. We offer standard colors like red, yellow, green, and blue for phase identification. Custom colors and printed markings are also available for batch orders. -
Q: What is the lead time for custom orders?
A: Lead times for custom sizes, colors, or prints vary based on order quantity and specifications. Generally, samples can be prepared within 7-10 working days, and production for larger orders within 3-4 weeks. Contact us for a precise quote. -
Q: Do you provide samples for testing?
A: Yes, we can provide sample lengths for evaluation and testing purposes. Please contact our sales team with your requirements. -
Q: How does the flame-retardant property work?
A: The specially formulated polyolefin contains additives that inhibit combustion. When exposed to flame, it chars and self-extinguishes quickly once the flame source is removed, helping to contain fire spread.
