The cable glands of the HV1203-PVC-BK-M1 series from HellermannTyton are designed for mechanical protection of cables and wiring at penetrations and exits. They are specifically designed for use in installations where cables pass through sharp edges or rough surfaces, providing reliable protection against mechanical damage. The glands are made of PVC material and are black in colour, making them suitable for various applications in electrical and IT installations.

Protection function
The main function of the glands is to protect cables from sharp edges that may occur when passing through enclosures, wall penetrations or other components. The flexible, rubber-like structure prevents direct contact between the cable jacket and the sharp edge. This avoids cracks, cuts or abrasion on the cable jacket, which could lead to insulation faults or short circuits.

Tension relief
Another key advantage is the integrated tension relief. During installation or later maintenance, cables are often under tension, especially when routed through narrow openings or fixings. The glands absorb this load by diverting the tension from the cable to the surrounding structure (e.g. the enclosure). This reduces mechanical stress on the cable and extends its service life.

Material and processing
The glands are made of PVC, a material known for its flexibility, chemical resistance and durability against environmental influences. The flexible structure allows for easy installation, as the glands can adapt to the shape of the penetration and be inserted into the opening without tools. Processing is therefore quick and requires no additional tools.

Resistance to chemicals and environmental influences
The PVC material exhibits excellent resistance to various chemicals, including oils, fats and common cleaning agents. It is also resistant to UV radiation and changing weather conditions, making the glands suitable for use in both indoor and outdoor environments. The material quality ensures a long service life under normal operating conditions.

Applications
The glands are used in a wide range of installation scenarios, particularly where cables pass through enclosures, switch cabinets, wall penetrations or machinery. They are common in electrical installations, IT infrastructure, automation technology and industrial manufacturing. Their universal applicability results from the combination of mechanical protection, tension relief and chemical resistance.

Compatibility and accessories
The glands are designed for standard penetrations and fit into most common openings in electrical and IT enclosures. They can be used with various cable types, as long as the cable diameters are within the specified tolerances. Installation requires no additional tools or accessories, reducing installation time and minimizing the risk of errors.

Operational benefits
In operation, the glands ensure increased safety and reliability of cable connections. By preventing mechanical damage and relieving tension, the likelihood of faults or failures is reduced. The easy installation and maintenance reduce labour effort and contribute to installation efficiency. The chemical resistance also ensures long-term functionality even in demanding environments.
