For the first time, high-voltage P-laser cables are used in Italian transmission grids

On Friday, Prysmian Group began testing the first transmission system
using a high-voltage P-laser cable.

P-lasers are the first type of high-performance environmentally friendly cables
for power grids.
Consisting of recyclable raw materials, these cables reduce the environmental impact of the grid while enhancing transmission performance
.
High-voltage P-laser cables retain the same power properties, are compatible with existing power grids, and have a low
environmental impact.
In fact, these cables can operate at temperatures higher than conventional cross-linked polyethylene (90°C); In addition, the materials used for the ground shield, the metal conductors and the outer shield are completely recyclable
.

The 150 kV, 5 km transmission line in Lacchiarella, near Milan, Italy, owned by the Terna Group, is an important basis
for the restructuring of the high-voltage transmission grid in the southwestern region of Milan.
The new instrument "PryCam" developed by Prysmian is installed at both ends
of the P-laser section about half a kilometre long.
The new instrument monitors and accurately detects any pulse signals generated by partial discharges, allowing different parts of the grid to be monitored without switching, avoiding failures and associated costs
.

After being certified by the Italian Institute of Quality Mark (IMQ), approved and recognized by Italian institutions, medium-voltage P-laser cables will also be applied to other European countries, such as the Netherlands and Spain
.
At present, these countries have started production and marketing, and satisfactory results
have been obtained.

P-Laser: an innovative technology in the cable industry

In 2008, Prysmian made significant progress in the development of P-laser technology: its innovation was significant in the distribution of electricity
for utilities.
From a technical point of view, the P-laser is made of an insulating system of thermoplastic materials, making the process more competitive, and the P-laser can be manufactured by only one production line without interruption, thus greatly reducing the delivery time
of the factory.
P-laser products are developed by Prysmian laboratories using high-performance thermoplastic elastomer compounds (HPTE) and have been granted a number of patents and patent applications
.
It can also be produced
according to different configuration requirements of metal shields and outer sheaths.
The P-laser architecture is compact, recyclable and compatible with conventional cables and accessories: P-laser products undoubtedly have more opportunities
for utilities that are increasingly focusing on eco-sustainable growth strategies.
