90c 4cx50mm2 XLPE insulated cable
What is XLPE cable?
XLPE cable stands for cross-linked polyethylene cable. It is a hydraulic pipe made of polyethylene plastic. XLPE has a 3D molecular bond structure and shape memory properties.

What are the benefits of XLPE?
XLPE insulation can play a role in both high and low temperatures. Due to its structure, XLPE is extremely resistant to abrasion and other wear. It also has the ability to withstand high voltage electricity, chemicals and other harmful substances. Cross-linked polyethylene insulation is also a more affordable option.
When should XLPE cables be used?
In short, XLPE cables are used in industries where wires and cables are exposed to the following conditions:
Extreme temperature conditions (high and low temperature)
High voltage electrical applications
Wear and stress
Water and other liquids
Chemicals and other harmful substances
XLPE cables can be used in plumbing, mining and various electrical applications. XLPE cables can also be found throughout the chemical industry as well as in the commercial and residential heating industry. Don't forget the ground maintenance of the dentist's office and other medical institutions, stadiums and other places, etc.
What is the difference between XLPE insulation and PVC insulation?
As mentioned above, XLPE is a cross-linked polyethylene material. PVC stands for polyvinyl chloride insulation.
The main difference between the two is that XLPE can be used for high tension and low tension applications. Its structure has good wear resistance, stress resistance and other wear resistance. PVC insulation material cannot withstand that much pressure, which means it is only suitable for low tension applications.
Other differences:
The life of XLPE insulation is longer than that of PVC insulation
Since XLPE does not contain chloride, it is more environmentally friendly
XLPE insulation can withstand higher temperatures
Cross-linked polyethylene has higher moisture resistance
