CORE PERFORMANCE

Why Melamine Laminated Tubes

Engineered for electrical safety in high-energy circuits — outperforming ceramics where arcs, heat and vibration meet.

01

Superior Arc Resistance

Resists carbonization under arc temperature from short-circuit interruption, assisting rapid arc quenching. G9 grade for high-energy DC scenarios.

02

Stable Insulation, Moisture Proof

Melamine tubes stay stable in hot-humid service — ideal for outdoor PV and on-board environments.

03

High Temperature & UL94-V0

Long-term service around 150–180℃ with UL94-V0 flame retardance — no burning or cracking under instantaneous arc heat.

04

Strong Mechanics, Vibration Proof

Glass-fiber reinforced structure outperforms brittle ceramics. Dimensionally stable through thermal cycles — ideal for vehicles and rail transit. Precision machined for high assembly yield.

05

Chemical Resistance

Resists weak acids, alkalis and oils — no media erosion or aging inside e-controls and battery packs.

06

RoHS Halogen-free Compliant

Halogen-free per RoHS available — friendly to EV, PV and rail transit project access.
