Helagaine Twist-In-EMIZ is a high performance, self closing EMI shielding sleeve made of tinned copper and polyester monofilament.

Key benefits at a glance:
- 60 dB EMC shielding for highly effective attenuation of EMI
- Patented System Z for enhanced shielding efficiency
- Certified EN45545 2: R22 HL3, R23 HL3
- Strong resistance to abrasion, vibration, impact and salt spray
- Lightweight, flexible, repositionable and designed for quick, easy installation
- Operating temperature: 65 °C to +150 °C

In modern rail vehicles, multiple electronic systems run in parallel – signalling, communication, control and passenger information. Electromagnetic interference (EMI) can disrupt sensitive cables, electronics components and impact system reliability. For effective EMI protection, grounding at both ends is recommended (ideally with 360° shielding on metal connectors).
