Polycab Solar H1Z2Z2-K Twin Cable – Flat Twin PV DC Cable, E-Beam Cross-Linked, Halogen-Free

The Polycab Solar H1Z2Z2-K Twin Cable is a flat twin parallel photovoltaic cable that carries the positive and negative of a string in one run, with electron-beam cross-linked, low-smoke, halogen-free insulation and sheath. Polycab's catalogue lists it under EN 50618 (type H1Z2Z2-K). It is supplied at a price on request: cable prices depend on the construction, the quantity and the raw-material prices on the day.

Polycab India Limited is India's largest manufacturer of wires and cables, with 27 manufacturing facilities, a network of 4,300+ dealers and distributors, 2,00,000+ retailers and an export presence in 84 countries (polycab.com, October 2026). Its cable range runs from house wires and 1.1 kV power and control cables to MV and EHV power cables, with instrumentation, solar, railway, marine, mining, fire-survival and other special cables. Jai Enterprises supplies Polycab cables from Bhilai and Raipur all over Chhattisgarh - Bhilai, Raipur, Durg, Korba, Bilaspur, Raigarh, Jagdalpur, Kanker, Ambikapur and every other district - and across India.

Is this the right one for you?

Check these four things before you order:

• The cable is for the DC side of a PV system.
• A paired positive-and-negative run suits your layout.
• You have sized the cores for at least 1.25 times the module short-circuit current (or for the string fuse rating, where strings are fused), and for voltage drop.
• Your specification accepts a twin construction (EN 50618 itself covers single-core cables).

Why choose the Polycab Solar H1Z2Z2-K Twin Cable

• Positive and negative in one flat cable - one run instead of two
• Electron-beam cross-linked, halogen-free, low-smoke insulation and sheath
• Flexible copper conductors
• For permanent outdoor use

How to choose and specify it

When to use the twin. A flat twin carries the positive and negative of a string in one run, which saves time on rooftop and small systems and keeps the loop area small.

Designation. In H1Z2Z2-K, H1 marks a harmonised cable for 1.5 kV DC, the two Z2s a halogen-free cross-linked insulation and sheath, and K a flexible class 5 conductor (as cable makers explain the code).

Installation. Separate the two cores only as far as the connectors need, use PV connectors matched to the cable, mate only plugs and sockets of the same type and make, crimp the contacts only with the tool the connector maker specifies, and protect the run from sharp edges. Solar DC cables for the module and string side are rated for DC voltage (1.5 kV DC under EN 50618), for sunlight and for outdoor service; ordinary PVC building wire is not.

Where it is used

• Home and commercial rooftop solar
• Small ground-mounted and off-grid systems
• Solar pumps and street-light panels
• Module leads to micro-inverters, and strings to string inverters
• Short paired runs between modules and combiner boxes

Frequently asked questions

What is the price of the Polycab Solar H1Z2Z2-K Twin Cable?

The Polycab Solar H1Z2Z2-K Twin Cable is supplied at a price on request, because cable prices depend on the construction, the quantity and the raw-material prices on the day. Call +91 9340081159 for a quotation.

What does H1Z2Z2-K mean?

It is the EN 50618 type code: H1 for a harmonised 1.5 kV DC cable, Z2 for halogen-free cross-linked insulation and sheath, and K for a flexible (class 5) conductor.

Why choose a twin instead of two single cores?

It lays both polarities in one run, which is quicker to install and keeps the loop area small.

Is the twin covered by EN 50618?

EN 50618 is written for single-core cables. The catalogue lists this flat twin under EN 50618; we confirm with Polycab how it is tested and marked.

Where can I buy the Polycab Solar H1Z2Z2-K Twin Cable in Chhattisgarh?

From Jai Enterprises, Bhilai and Raipur, which supplies Polycab cables to every district of Chhattisgarh and across India. Call +91 9340081159 for the price, stock and lead time.
