HPL Solar Cables

INTRODUCTION

SOLAR CABLE is nervous systems of a Solar power plant from panels to invertor and, therefore, one of the most crucial parts.

They are connected on DC side of the system, proper cable sizing and its quality ultimately decides the power delivered to the load and in turn efficiency of the entire system because undersized cable results into heating which may lead further up to hazardous incidents like fire.

Also even a small increase in cable resistance resulting into increased I²R losses which is considered as a higher loss of energy and such cable will lose its acceptance.

Further as solar cable has to function in open atmosphere over a long period, it has to withstand all environmental severities like UV radiation, rain, dust & dirt, temperature variations, humidity, insects and microbes etc. frequent failure / replacement of solar cable will lead to decrease in the overall project efficiency resulting in high operational costs.

HP Solar cables are made under stringent MNRE parameters to deliver lasting performance throughout the lifetime of the PV system.

Special Properties of HPL Solar Cables

• UV resistance: full protection against ultraviolet rays.
• Outdoor durability: resists extreme temperatures (-40^◦C to 120^◦C) and ozone resistant.
• Halogen-free: Low Smoke Emission & Low Toxicity/Corrosively during fire.
• Properties against fire: flame retardant, fire retardant.
• Flexibility and stripping ability: for fast and easy installation.
• Lifetime and stripping ability: lasts up to 30 years even under tough external conditions.
• Fully recyclable: in accordance with new environmental regulations.
• Suitable to any connector types.
• According to EN/IEC/IS.
