Purchase Single Core or Twin Core Photovoltaic Cable?

Due to the vigorous development of new energy sources worldwide in recent years, and the support of various countries, and then favored by many famous capitals all over the world, definitely photovoltaic solar power plants have a very broad development prospects. Not only that, street lights, water heaters on the house roof, car charging, etc. are also accelerating the application of solar charging technology. Among them, photovoltaic cables are also very important components in photovoltaic design.

Therefore, in recent years, wire and cable buyers are purchasing photovoltaic cables more and more, and the quality requirements are getting higher and higher, and the questions asked are various, such as some buyers or engineering Businessmen like to ask how many cores the photovoltaic cable has.

Indeed, to understand the number of cores of the photovoltaic cable is also helpful to the construction of the project, let's take a look at how many cores the general photovoltaic cable or solar dc wire has.

Single Core or Twin Core

In general there are 2 kinds of photovoltaic cables, they are PV1-F solar dc wires and H1 Z2Z2-K cables. Both of these photovoltaic cables are composed of one core and two cores. However, the special solar dc wire consist of multiple strands of tinned copper in one core. Customer-customized multi-core photovoltaic special cables, generally 6 cores, please contact the solar pv wire manufacturer of solar dc wires or cables for details, the outer layer of multi-core conductor photovoltaic special cables has PVC insulation and radiation cross-linked polyolefin outer sheath composition, the outer layer of polyvinyl chloride is what we call nylon sheath. In general the single core more purchased compared to the twin core photovoltaic cable.

PV1-F or H1Z2Z2-K

What is the difference between PV1-F cables and H1 Z2Z2-K solar dc wires or cables? Actually it is so easy to distinguish the PV1-F cables and H1 Z2Z2-K photovoltaic cable, the sole difference between them is the standard, the PV1-F solar dc wire is produced by the IEC standard compared to the H1Z2Z2-K is manufactured by the European standard. The insulation material both need the low smoke zero halogen xlpe, apart from the conductor both adopt the stranded tinned copper. 

The conductor core of the special photovoltaic cable is composed of multiple strands. However, the conductivity of this special photovoltaic cable is relatively fast. This is a special photovoltaic cable designed based on power transmission, and there is also a high-temperature radiation cross-linked polyolefin. The sheath is made to allow the photovoltaic power to be installed and used in different environments.

The above is the introduction of "the number of cores in photovoltaic cables or solar dc wire" and hope this article could help lots of foreign purchasers and buyers for buying the photovoltaic cable. Please continue to pay attention to JZD Cable for more useful information about solar cable.
