Van Damme SDI Vision LSZH SDI Cable — 278075000
The Van Damme SDI Vision 278075000 is a precision 75 ohm LSZH SDI cable built for fixed broadcast and AV installations in regulated environments where Low Smoke Zero Halogen cable is a code requirement or a project specification. Part of Van Damme’s SDI Vision Ecoflex range, the 278075000 delivers reliable SMPTE 259M SDI and analogue video performance with the added protection of an SHF-1 LSZH thermoplastic polymer outer jacket — a material chosen specifically for installations in public buildings, government premises, schools and universities, marine vessels, and any environment where fire safety regulations mandate low smoke, zero halogen cable construction.
The 278075000 is a single coaxial at 4.50 mm overall diameter — compact, manageable, and designed to route cleanly through conduit, cable tray, and structured building cabling infrastructure. While it supports primary SDI and analogue video transmission as its core function, it is also rated for shorter distance 3 Gb/s HD-SDI runs where the installation requires LSZH compliance alongside SDI performance. This is the correct cable choice when both signal specification and building compliance requirements need to be satisfied by the same cable.
Why LSZH Cable Is Specified — and When It Is Mandatory
Standard coaxial cables use PVC or PVC-composite outer jackets. PVC is a cost-effective and mechanically capable jacket material that performs well in the majority of professional AV and broadcast applications. Its limitation becomes critical in fire conditions: PVC burns with dense black smoke and releases halogen gases — primarily hydrogen chloride — that are toxic to building occupants and highly corrosive to electronics, communications equipment, and infrastructure in the surrounding area.
Low Smoke Zero Halogen cable construction addresses both failure modes. In fire conditions, LSZH materials produce significantly less smoke than PVC — maintaining visibility in escape routes for longer, which is measurable in survival outcomes during building evacuations. LSZH materials do not release halogen acids, removing the secondary risk of acid gas corrosion to electronics infrastructure that can extend the damage footprint of a fire well beyond the immediate burn area.
In South Africa and internationally, LSZH cable is either mandated or strongly recommended in a range of installation environments. Public buildings with large occupant loads — shopping centres, conference facilities, theatres — frequently specify LSZH for all cabling in occupied spaces. Government premises, educational institutions, hospitals, and marine vessel installations commonly require LSZH cable by specification or by the applicable building or marine standard. The 278075000 is fully tested and compliant with the relevant IEC fire safety standards governing LSZH cable: IEC 60332-1 for fire retardancy of a single cable, IEC 60754-1 and -2 for halogen gas emissions and acidity, and IEC 61034-2 for smoke density measurement.
Precision 75 Ohm Electrical Performance
The electrical construction of the 278075000 follows the same exacting approach Van Damme applies across the HDVision and SDI Vision coaxial ranges. The centre conductor is 1 × 0.60 mm bare ultra-pure oxygen-free copper at AWG 23 — a solid conductor chosen for its low signal loss characteristics over the SDI transmission distances typical of fixed building infrastructure. The foam skin polyethylene dielectric at 2.80 mm diameter provides the controlled impedance environment required for consistent 75 ohm performance from connector to connector across the full cable run.
The screening architecture uses two layers for thorough signal protection: an aluminium and polyester foil screen at 125% coverage as the primary screen, and a tinned braided oxygen-free copper secondary screen at greater than 95% coverage. Dual screening provides better overall electromagnetic isolation than a single screen alone — the foil delivers complete coverage continuity, while the braid provides structural strength to the screen and ensures low-impedance return current path continuity under bending and installation stress.
The 4.50 mm overall diameter is a deliberate design choice for an installation cable. At this size, the 278075000 routes through conduit easily, fits standard BNC crimp connectors without requiring oversize tooling, and can be installed in high-density cable trays alongside other structured cabling without excessive bulk. The 15 × overall diameter bend radius is appropriate for a fixed installation cable of this type — tighter bends than this radius should be avoided to protect the solid centre conductor and maintain impedance consistency at the bend point.
LSZH SDI Cable for Broadcast and Fixed AV Infrastructure
The 278075000 occupies a specific and important position in the Van Damme coaxial range: it is the product for projects where standard SDI cable specification meets regulated installation requirements. A broadcast facility installed in a government building, a university AV system, a hospital audio-visual infrastructure project, or an SDI video distribution system in a public venue — these are the projects where the 278075000 resolves the specification challenge of meeting both broadcast signal performance and building code compliance requirements simultaneously.
The water blue RAL 5021 jacket colour is a standard identifier for LSZH cable in professional AV and broadcast infrastructure, distinguishing the 278075000 visually from the jet black standard PVC coaxial cables in the Van Damme range. In a structured installation with mixed cable types, colour identification reduces maintenance and fault-finding time significantly.
