Frequently Asked Questions
Q1: What is the key advantage of CW type compression glands over standard glands?
CW type compression glands provide superior cable retention through mechanical compression, offering better vibration resistance, enhanced sealing performance, and more reliable grounding continuity compared to standard cable glands, making them ideal for demanding industrial applications.
Q2: How does the compression mechanism work in CW type glands?
The compression mechanism uses a specially designed compression ring that gets compressed between the gland body and compression nut, creating radial force that grips the cable securely while maintaining seal integrity and providing excellent electromagnetic shielding.
Q3: Are CW type compression glands suitable for armored cables?
Yes, our CW type compression glands are specifically designed for both armored and non-armored cables. For armored cables, they provide secure armor clamping and maintain earth continuity, while for non-armored cables, they offer superior cable retention and environmental protection.
Q4: What certifications do your explosion proof CW compression glands carry?
Our explosion proof CW compression glands are ATEX certified for Zone 1 and Zone 2 hazardous areas, IECEx certified for international markets, and carry UL and CSA approvals for North American requirements.
Q5: What is the maximum cable diameter your CW glands can accommodate?
Our CW type compression glands accommodate cable diameters from 3mm to 54mm, with specific size ranges for each gland variant. We provide comprehensive cable range tables for proper selection.
Q6: Can you provide custom-colored compression glands?
Yes, we offer custom color options for specific project requirements. We recommend standard nickel-plated finish for maximum corrosion resistance, but can provide colored epoxy coatings with minimum order quantities.
