What’s the feature of 11kv cable 240mm?
11kv cable 240mm as a kinds of the medium voltage cable. 11kv cable 630mm is made of cross linked polyethylene (xlpe) or polyvinyl chloride (PVC) materials.
3 core xlpe GSW armoured cable
Single core xlpe SWA armoured cable
Especially, the xlpe insulation has superior thermal extension performance and strong current shielding. And the xlpe insulation material widely used for the production of the 11kv xlpe cable. Usually, the xlpe material’s temperature up to 90 degree. And then, it is going to operate at extremely high temperature of the 11kv cable 120mm .
Thereby, the 11kv cable 300mm is very popular in nowadays. The 11kv cable 240mm is not only a very proper suited for direct burial, underground conduit program, public place and so on. But a few people know its another name, it is the one 11kv underground cable. And this type 11kv cable 185mm is becoming much more common. So, more and more people are used to calling it as 11kv cable 95mm. So, when you want to learn a cable’s feature, you not only know its kinds of names, but also know 11kv cable 630mm structure, materials and application etc.
Which type of 3 core xlpe cable is used for 11 kv?

Application of the difference types of 11kv cable 185mm – 630mm
Although, we name the 11kv cable 240mm- 630mm refers to the 11kv cable 95mm. But, usually 11kv cable 300mm-185mm has two types non-armoured and armoured. And the armoured also including steel tape armoured (sta) 11kv xlpe cable and steel wire armoured or galvanize steel wire armoured xlpe insulation11kv cable. But the GSW armoured layer only suitable to the 11kv 3 core xlpe cable. And the ATA armoured and SWA armoured layer only use to the single core 11kv cable 120mm.
But If we notice the structure. We name the 4 core 240 mm cable as single core xlpe insulation 11kv cable 185mm with aluminum tape armoured layer and the 11kv 3 core xlpe cable with sta and swa armoured layer.
Meanwhile, we name also the 11kv underground cable as 11kv armoured cable. And the armoured 11kv xlpe cable is very suitable to the underground install, power substation project, building and so on. If you are looking for the 11kv 3 core xlpe cable, you can contact Huadong Cable Company. We will provide the best competitive 11kv xlpe cable price list for you reference. At the same time, our special 11kv cable 120mm engineer will free design the structure according to your requirement. And free the 11kv cable 95mm cable sample.

What is the influence 3 core 11kv xlpe cable price?
All know, the price is always an essential factor to consider when you choose 11kv xlpe cable. Generally, 11kV xlpe cable price varies depending on the following factors
Firstly, Copper and Aluminum materials price:
The copper and aluminum material raw material price is one of the most important factors that influence the price of 11kv xlpe cable. That means the 11kv xlpe cable price is determined by the cost of copper with the increase or decrease in copper price. So the 95mm 120mm 630mm 3 240mm 300mm 11xlpe cable price will also change accordingly. We don’t have a specific price.
Secondly, 11kv xlpe cable price depends on the difference sizes
The 11kv 15kv cable cost per meter is determined by the square number of its total area, divided by the usable length. For example, a 240mm cable is more expensive than a 185mm xlpe cable. If you want to know 11kv 3 core XLPE cable price, you are welcome to contact Huadong cable group. At any moment, we may update the price.
Size is another crucial factor that affects the 11kv xlpe cable price. The larger the size of the cable, the higher the price will be. For example, 11kv 240mm cable price is usually higher than 185mm 11kv xlpe cable price. However, the price difference is not always significant. It all depends on the market situation.
