Solar DC Cables

 
Solar DC Cables Introduction

Introduction

 

Divine Energy Inc DC Solar cables are designed for connecting photovoltaic power supply systems. They are dedicated to the photovoltaic system direct current (D.C.) side with a nominal D.C. voltage of a 1.5kV. These cables can be used indoor & outdoor for flexible and fixed installations with high mechanical strength in extreme weather conditions. Cables are designed to withstand the demanding environmental conditions that arise in any fixed, mobile, roof or architecturally integrated photovoltaic installation. They are suitable for applications in equipment with protective insulation (protecting Class 2).

 
 

Specifications

 

As per TUV Rheinland specification: 2 Pfg 1169/08.2007.

 

Solar Cables used in Solar Farm installations are mainly categorized as given below:

 

A) PV module to PV module and PV modules to Array Junction Box

 

These cables though not exposed to direct sunlight are throughout the day time exposed to diffused/indirect sunlight and atmospheric temperatures in open air.

 
 
 
Type 01

TYPE 1

 

DC Solar Cables are Single core Copper cables each for +ve and —ve. They are insulated and sheathed with Cross Linkable LSOH which has UV as well as Ozone protection properties. These cables confirm to TUV specifications.

 
Type 02

TYPE 2

 

DC Solar Cables are Single core Copper cables each for +ve and —ve. They are insulated with HR 105°C PVC compound and sheathed with UV stabilized HR 105°C PVC compound.

 
Type 03

TYPE 3

 

DC Solar Cables are Single core Copper cables each for +ve and —ve. They are insulated with XLPE compound and and sheathed with UV stabilized PVC ST2 compound.

 
 
 

B) Array Junction Box to Main Junction Box and Main

 

These Solar DC cables which are not exposed to sunlight and are always routed through PVC Pipes which are laid underground. Choice of cables can be done from any one of the options given. Generally Option 3 is chosen for this route.

 
Cable B
 
 
Cable C
 

C) Inverter to Transformer Primary

 

The Three Phase AC output from the Inverters is connected to the Transformer Primary through Underground Armoured Cables. These cables are Copper or Aluminium XLPE insulated, GI armoured, UV stabilised PVC ST2.

 
 
 
 

D) Transformer Secondary to RMU/Switchyard

 

The Three Phase AC output from the Tranformer Secondary is connected to the RMU/Switchyard through Armoured Cables. These cables are Copper or Aluminium XLPE insulated, GI armoured, UV stabilised PVC ST2.

 
Cable D
 
 
Cable E
 

E) RMU to Switchyard

 

Three Phase AC connection from the RMU is connected to the Switchyard through Armoured Cables. These cables are Copper or Aluminium XLPE insulated, GI armoured, UV stabilised PVC ST2.

 
 
 

Note:

 

All Solar cables used with XLPE insulation armoured or unarmoured are specially manufactured with UV stabilised PVC ST2 outer sheathing which are specially formulated compounds to sustain the Direct / Diffused / Indirect Sunlight in case of exposed cables at any stage of installation.

 
 
 

Solar DC Cable

 

After hydro and wind power, the third most important renewable energy source is solar photovoltaic in items of globally installed capacity. This results in the great demand for ‘SOLAR CABLE’. Solar cables are exclusively made for applications in photovoltaic power systems. A solar cable interconnects solar panels and other electrical components of photovoltaic system. These solar cables are designed to be UV & Ozone resistant, Chemical and Oil resistant, with excellent FR properties, propagates smoke with low capacity when burned with external source and contains absolutely ZERO or low halogen. These cable can survive extreme weather conditions. It can be used within a large temperature range and are generally laid outside. These cable can be installed at indoor in hazard area, in explosion areas, in industry and in agriculture. These cables are environment friendly which performs highest standards of application in its diverse usage.

 
 

Insulation

 

Solar cable must be insulated to withstand thermal and mechanical loads. As a consequence, plastics which have been cross-linkable Silicon / Electron Beam feature are increasingly used. The insulation and double-jacketed materials are extremely resistant to weathering, UV-radiation and abrasion. Additionally, it is salt water resistant and resistant to acids and alkaline solutions. It is suitable for fixed installation as well as for moving applications without tensile load. It is especially designed for outdoor use, which means direct sun radiation and air humidity, but due to the halogen free flame retardant cross-linked jacket material the cable can also be installed in dry and humid conditions indoors.
