High Temperature Cable Gland
In industrial, automotive, and energy applications where cables are exposed to prolonged high temperatures—such as near engines, furnaces, or exhaust systems—standard cable glands fail to provide adequate protection. High temperature cable glands are specialized components designed to maintain secure, sealed cable connections in extreme heat, ensuring reliable performance without compromising safety or functionality.
A high temperature cable gland, also known as a heat-resistant cable gland or thermal-resistant cable connector, is a mechanical device designed to terminate, seal, and secure cables in environments where temperatures exceed the capabilities of standard glands. Key functions include:
Thermal Stability: Withstanding continuous operating temperatures up to +260°C (short-term peaks to +300°C) without material degradation.
Secure Sealing: Maintaining IP65-IP68 ratings even in thermal cycling conditions, preventing dust, moisture, and corrosive gases from entering cable terminations.
Mechanical Reinforcement: Providing strain relief for cables subjected to vibration or thermal expansion/contraction in high-heat zones.

FAQ：
How to Select the Right High Temperature Cable Gland ?
Define Temperature Requirements
Continuous vs. Peak Temperature: Ensure the gland's CTI (Continuous Temperature Index) exceeds your application's average operating temp by 20°C (e.g., +180°C gland for +160°C environment).
Thermal Exposure Duration: Short-term peaks (e.g., engine start-up spikes) vs. 24/7 high-temp operation (e.g., furnace control systems).
Match Cable & Environment
Cable Sheath Material:
PTFE (up to +260°C): Use PEEK or stainless steel glands with compatible sealing profiles.
PVC (up to +105°C): Nylon glands with FKM seals suffice for moderate heat.
Chemical Exposure: In petrochemical plants, choose glands with fluoropolymer coatings to resist sulfuric acid at +150°C.
Certifications & Compliance
UL 746C: Verifies polymer thermal stability (e.g., PPS rated for +200°C under UL).
IEC 60529 (IP Rating): Ensure IP66/IP68 ratings are maintained at max operating temp (some glands lose sealing at +180°C+).
RoHS 2.0/REACH: Critical for European industrial applications; avoid glands with cadmium-based heat stabilizers.
Mechanical & Installation Features
Strain Relief Design: Glands with helical spring inserts reduce vibration-induced stress on cables in high-temp machinery (e.g., compressors).
Quick-Release Threads: Stainless steel glands with anti-seize coatings (e.g., molybdenum disulfide) simplify maintenance in hard-to-reach hot spots.
