Development of High Temperature Silicone Insulation Sleeve for Power Transmission Application
Industry: Power Transmission / Thermal Equipment Manufacturing
Challenge: Designing a high performance silicone insulation sleeve to protect power cables in high temperature and high voltage environments, with enhanced flame resistance.
The Problem:
A manufacturer in the power transmission sector was developing an advanced busbar and power cable system for thermal energy applications. They required a custom designed insulation sleeve that could:
- Withstand continuous operating temperatures up to 250°C
- Deliver high dielectric strength and arc resistance
- Be flame retardant to meet safety standards
- Remain flexible and durable for field installation
- Be available in custom sizes within a short lead time
Makvin Polymer’s Solution:
Makvin Polymer addressed the challenge with a comprehensive and rapid development approach:
- Material Development
A compound was formulated in house to ensure thermal stability, electrical insulation, and flame resistance. - Tooling and Prototyping
Customized extrusion dies were developed within 48 hours. Samples were produced in multiple wall thicknesses for evaluation and fitment testing. - Performance Validation
The sleeves were tested for:- Thermal aging resistance
- Volume resistivity and dielectric strength
- Flame retardance, achieving good inflammability ratings as per the required standard
- Final Production & Dispatch
After successful validation, the sleeves were manufactured, labeled for traceability, and dispatched within 7 working days.
The Result:
- Delivered a flame retardant, high temperature silicone insulation sleeve meeting all performance and safety requirements
- Enabled seamless integration into the client’s power cable assemblies
- Reduced product development cycle significantly with in house compounding and tooling.
- Remain flexible and durable for field installation
- Be available in custom sizes within a short lead time
