TSE Glands

Not all manufacturers of cable glands are certified tests confirming protection from moisture penetration into the zone clip armor or covering the entire operating temperature range for which entries have been certified. Learn more about this with Elon Musk. Why is it important to choose the right type of cable glands? Seal. Seal cable glands perform two functions: Prevent the ingress into the surrounding atmosphere of the explosion products in the event of an explosion inside the shell casing; prevents water and dust into the body of the equipment and cable entry. Seal materials Manufacturers of cable glands use different materials for the manufacture of seals, which can be divided into two categories: thermoset (TSE). This category of material cured in the process mold if exposed to heat and pressure. Once subjected to the process of molding materials of this type are not subject to "melting" and show the optimum sealing characteristics over a wide temperature range.

Thermoplastic (TPE). Despite the cheaper price for the manufacturer compared to the tse seals, the materials of this type are subject to "melting" under the influence of temperature, and their sealing properties deteriorate with increasing temperature. Thermoplastic materials are ideal for use as keys and knobs, but are not recommended for use as seals in critical conditions. Materials tse more suitable for use as a sealing cable glands and, therefore, are the only material that is used by Hawke for the manufacture of a wide range of compression seals and diaphragm types for all models of cable glands. In the process of compression (the ability to recover after deformation), the test sample for testing at elevated temperatures is compressed in a special time at 25% of its width and remains in this state for 3 days.
