If your office or residence is located in an urban area of London, it’s mandatory to follow the legally approved cable-laying techniques. Their installation demands proper planning, attention to detail, and the use of the right tools. That’s why choosing one from the various cable laying services in London seems difficult for individuals. So here, the experts from London are sharing some lessons to get the cable laying done in the right manner.
Types of Cable-Laying
There are three kinds of cable-laying techniques which are given below,
Direct Laying
Direct laying is a very effective cable-laying technique for ensuring the proper power flow in certain areas where grounds enable direct burial with no need for extra ducts. Under this technique, the experts dig the ground for at least 1.5m deep and 0.45 m wide trench to fix the power cables.
After that, a bed of sand is put at the bottom of an almost 10 cm thick layer. Now, to keep it protected from any damage, bricks and other necessary materials are used. As a result, not only does it save your time but also demands fewer resources to get the work done.
Pros
It’s the most convenient and cheapest method for underground cable laying.
All the heat produced under this will immerse directly into the ground.
Cons
The maintenance cost is high.
Finding the location of faults can be very difficult.
Altering cable network connections will be tough.
Draw-in System
A draw-in system is another way of cable-laying for seamless power transfer. This system will make use of duct pipes and sometimes conduits to create safe pathways of cables and provide better protection. What a professional will do is use ducts or conduits made of cast iron concrete and glazed stone with manholes. They are put at appropriate locations following the cable pathways.
Advantages:
The use of manholes will help to ease repair and maintenance tasks.
Significantly reduces the maintenance cost.
The probability of faults is reduced due to mechanical protection.
Disadvantages:
Installation will cost a large amount.
Grouped cables help in low heat dispersion.
Solid system
In the solid system cable laying service, the cables are set in open pipes or troughs following the cable pathway. The professionals use asphalt which is used as a filler in the trough once the cable is fixed at the right position.
Advantages:
This system delivers strong mechanical protection.
Disadvantages
Skill and labor requirements result in high costs.
You will need a skilled labor force which can increase the cost.
Benefits
If you want an interrupted power supply in your residence and commercial property, keeping the infrastructure well-planned is pretty important. Go through the following points to understand the benefits of proper cable-laying:
Underground cables can sustain longer than aerial cables so it will ensure seamless transmission of power.
They will keep the maintenance costs lower by preventing damage from a falling tree or strong breeze.
Aerial cables can fall on buildings and cars which can put them at risk of getting electric shocks. That’s why underground cable laying sounds like the safest option.
Because the cables are layered with underground protection, you can keep receiving a continuous power supply.
Underground cables can save a lot of space because it doesn’t need any space for pole installation.
Challenges of underground cable laying
Although underground cable layering is beneficial in many ways, it comes with certain challenges:
Considering the cost, the underground cable system will be expensive as the roads will have to be restored.
It’s not easy to start underground cable laying because you will have to get legal permission from relevant authorities.
While routing the underground cable, many obstacles can come in the way so it should be done carefully.
