The Challenges

Large cable management icon for heavy gauge power cables

Large Cable Management

The Risk: Heavy-gauge power cables require exceptional clamping force to prevent twisting and pulling at the terminators, but over-tightening can damage insulation and cause hotspots.

Our Approach: Our large-diameter Metal Series (up to M110) is designed with precise clamping mechanisms that distribute pressure evenly, ensuring maximum strain relief without compromising cable insulation.

High load and EMI protection icon for power distribution cable glands

High Load & EMI Protection

The Risk: High-current power cables can generate significant electromagnetic interference (EMI), disrupting nearby control signals and degrading system efficiency.

Our Approach: We offer specialized EMC Shielded metal glands with integrated contact springs, certified to provide 360° EMI shielding and maintain signal purity in complex energy systems.

Extreme environment stability icon for power distribution cable glands

Extreme Environment Stability

The Risk: Offshore wind farms, coastal substations, and tropical power stations expose metal parts to relentless salt spray and high humidity, leading to corrosion and seal failure.

Our Approach: Our Stainless Steel 316L series passes a 1000h salt spray test, ensuring long-term IP68 protection in coastal and offshore power distribution networks.
