<h3>For long-term use in demanding environments</h3>
<p>The <strong>H1Z2Z2-K</strong> complies with <strong>DIN EN 50618 (VDE 0283-618)</strong> and is specifically designed for the <strong>cabling of photovoltaic systems</strong>. It can be <strong>installed permanently or used flexibly</strong> – indoors, outdoors, in industrial facilities, agricultural operations, or even in <strong>hazardous (explosive) areas</strong>. The cable is <strong>UV-, ozone- and water-resistant (AD7)</strong> and can be <strong>laid directly in the ground</strong>.</p>
<h3>Construction and technical features</h3>
<p>The finely stranded <strong>tinned copper conductor (class 5)</strong> is double protected by <strong>cross-linked insulation and a cross-linked outer sheath made of polyolefin copolymer</strong> – halogen-free, flame-retardant, and highly abrasion-resistant. The cable is designed for a maximum conductor temperature of <strong>120 °C</strong> and remains reliably flexible even at <strong>-40 °C (fixed installation)</strong>. Its <strong>low smoke emission</strong> and high resistance to mechanical and thermal stress ensure safe, long-term operation.</p>
