High Strength SMC MATERIAL for Busbar Supports | SUSDURA

For electrical busbar supports, passing flame, dielectric and insulation tests is only part of the challenge. When the finished component must resist severe tensile loading without cracking around fasteners or losing structural integrity, conventional electrical SMC may not provide enough mechanical margin. SUSDURA developed High Strength SMC using long glass fiber reinforcement to address precisely

From resin formulation to 1500°C thermal exposure testing, see how SUSDURA develops custom high flame-retardant SMC for demanding thermal environments

High Flame-Retardant SMC Material_SUSDURA

As electric vehicles, energy-storage systems and high-power electrical equipment become more energy-dense, conventional flame-retardant composites are being pushed beyond simple self-extinguishing requirements. Customers increasingly need high flame-retardant SMC material that can resist intense thermal exposure, delay flame penetration, control through-thickness degradation and maintain useful structural integrity. This challenge led SUSDURA to develop a customized thermal-barrier

Low Shrinkage SMC Material for Precision Components

Low Shrinkage SMC Material is increasingly important in switchgear, ACB, MCCB, busbar supports and precision electrical structures where electrical performance alone is no longer enough. A material may meet dielectric strength, CTI and flame-retardancy requirements yet still fail in production if molding shrinkage varies enough to shift hole positions, insert locations, flatness or assembly dimensions.

GPO3 Buying Guide: Sizes, Certifications & Suppliers

Buying GPO3 is more complicated than selecting a red fiberglass insulation sheet from a catalog. Two sheets that look similar can differ in thickness tolerance, flatness, electrical properties, flame performance, certification coverage and machining quality. For purchasing teams, the real challenge is defining exactly what the application needs—and then determining whether a distributor, GPO3 manufacturer

How SUSDURA Engineered a 2 mm SMC Electrical Enclosure / SMC Junction Box Panel to Meet IK10 Impact Requirements

A French power-industry customer required a large SMC electrical enclosure door panel measuring approximately 600 × 900 mm with a nominal wall thickness of only 2 mm. The challenge was not simply producing an SMC junction box, SMC junction cabinet, or SMC electrical cabinet. The finished enclosure also had to achieve the required IK10 electrical

BMC Material for Electrical Insulators: Properties, Requirements and Material Selection

Selecting a BMC material for electrical insulators requires more than comparing dielectric-strength values. A reliable BMC electrical insulator must combine electrical insulation, tracking resistance, mechanical load capacity, moisture resistance, flame behavior, dimensional stability and insert retention. Whether the application is a BMC standoff insulator, BMC busbar insulator, BMC busbar support or BMC switchgear insulator, the

Learn how to select SMC for electrical cabinets based on insulation, CTI, flame resistance, weathering, strength and dimensional stability.

SMC Material for Electrical Cabinets: Properties, Requirements and Material Selection

Selecting an SMC material for electrical cabinets involves far more than confirming that the material is electrically insulating. An SMC electrical cabinet or SMC electrical enclosure may also require tracking resistance, flame retardancy, mechanical strength, weather resistance, dimensional stability and predictable molding behavior. For this reason, the correct SMC material for electrical enclosure applications should
