When you think of energy new, what comes to mind? Energy new vehicles? Indeed, the sales of energy new vehicles in China go from 3.5 million in 2021 to 6.8 million in 2022. However, what I want to introduce today is the new energy new product ---PV cables. Have you ever seen a kind of cable that is both waterproof and fireproof? Do you know a kind of green non-polluting cable? Today we will take a look at the PV cables which belong to the energy new and are different from the common cable electric.

Ⅰ. What are PV cables?

PV cables are electrical conductors that connect the PV cells inside the solar panel to the rest of the solar power system. They carry the DC power generated by the solar panels to the inverters or batteries in the power station. The DC power is converted to AC power, which is used to charge appliances such as refrigerators, air conditioners, and electric grills. Although there are three types of cables, PV cable, USE-2 cables, and THHN cables, PV cables are the most widely used.

The characteristics of PV cables are determined by their cable-specific insulating and sheathing materials, which we call cross-linked PE. After irradiation by an irradiation gas pedal, the molecular structure of the cable material is changed to provide its individual properties. Resistance to mechanical loads. In fact, during installation and maintenance, cables can be routed on sharp edges of the roof structure, while they are subjected to pressure, bending, tension, cross-tensioning loads, and strong impacts. If the cable sheath is not strong enough, the cable insulation will be severely damaged, which can affect the service life of the entire cable or lead to problems such as short circuits, fires, and injury hazards.

When PV cables are used in conjunction with other PV modules for export to Europe, the cables must comply with the TUV MARK certificate issued by TUV Rheinland. At the end of 2012, TUV Rheinland Germany launched a series of new standards with PV modules, DC 1.5KV single-core wire, and PV AC multi-core wire.

Ⅱ. PV cables vs common electric cables

A. What is the difference between PV  cables and common electric cables?

1. Different raw materials:

PV cables:

Conductor: copper conductor or tinned copper wire conductor

Insulation: irradiated cross-linked polyolefin insulation

Sheath: irradiated cross-linked polyolefin insulation

Ordinary electric cables :

Conductor: copper conductor

Insulation: PVC or cross-linked polyethylene insulation

Sheath: polyvinyl chloride (PVC) sheath

2. Processing differences

The outer jacket of PV cables is cross-linked and irradiated, whereas ordinary cable electric is generally not irradiated.

Generally do not undergo irradiation.

3. Different use environments

PV cables are generally used outdoors in harsh environments. And ordinary electric cable is commonly used for indoor laying, buried piping electrical equipment connection, etc.

B. What are the advantages of  PV cables?

1. Long life, with all the characteristics of general solar cable

The cable sheath of common electric cables has poor anti-ultraviolet performance, which can easily lead to the aging of the cable sheath, thus affecting the service life of the cable.

PV cables: insulation and jacket of special materials have extended the service life of the cables, and can be used at 90 degrees Celsius below 25 years.

2. High-temperature resistance, UV protection

Common electric cables are buried deep in the environment which is better, and the general resistance to high temperatures is poor than the ability of the solar cable.

And PV cables due to the role of environmental requirements therefore must withstand high temperatures, because they are often exposed to direct sunlight. High temperatures have several potential hazards, which damage the cable's service life and lead to greater safety accidents.

4. Professional waterproof certification

62930 IEC/H1Z2Z2-K single-core solar cable has AD7 waterproof certification for wet, dark, and damp locations. It represents that it belongs to the waterproof.

It has a wide range of applications. It is a highly flexible cable, compatible with all major connectors, designed for connecting PV  panels. This versatile single-core cable is designed to meet the different needs of the solar industry.

We produce and supply both normal models and more reliable waterproof and fireproof models. We are able to provide you with the type of cable you need according to your requirements. Customized service, we always insist on user-centered and user needs. If you have any needs, we provide all after-sales services.

9. Specialization, reliable quality

a. Reliable enterprise + professional factory
The reliability and efficiency of solar cables are critical to the performance of a solar system. Poor-quality cables can lead to energy loss, lower system efficiency, and even safety hazards.
As a company specializing in the production of energy new cables, we have many international certifications. The production side of the company also has official certifications. The sales of 400 million a year are also a response to the quality. There is no hidden danger to safety.

b. Attentive service + participatory supervision

There are cable pre-assembly services, pre-sale, and after-sale services to escort your order.
In addition, to facilitate customers to participate in the production process, and to get a sense of participation and experience, we provide production visualization services, that is, to provide production, production planning, delivery, and loading diagrams
c. Short delivery time

10. Environmentally friendly

Solar energy has revolutionized the way we use energy. The current environmental and economic crisis is forcing us to look for renewable energy sources that do not affect the environment or people.
