lead sheathed electrical cable benefits VS cleat wiring
The sheathed type of electrical wire and cable is produced for safety reasons. Lead material as sheath VS the cleat for wiring can be compared in many aspects which each has its benefits and down sides.
lead sheathed electrical cable
On a variety of wire and cable insulations, a lead sheath is one of the available options. This sheath is entirely impervious to water and has a high level of durability.
When there is a need for both high levels of mechanical strength and resistance to moisture, one option is to utilize a combination of lead sheath and armor. In most cases, lead-sheathed cables are utilized in environments consisting of underground ducts and moist regions.
The primary benefit of using lead is that it can be extruded onto the cable core in lengths that are not limited, and this can be done at temperatures that do not cause damage to even the most delicate conductors (optical fibers) or insulating materials.
Lead also has a low melting point (paper or plastics). Since lead is malleable, it is able to survive the numerous coiling, uncoiling, handling, and bending operations that are involved in the final stages of cable manufacturing and installation.
When joining cable lengths together or installing new cables, a lead sheath can be easily soldered (yet again at low temperatures), which is necessary in both cases.
With the help of contemporary screw-type continuous extruders, it is possible to make unjointed stretches of undersea power cables that are as long as 100 kilometers.
Cables are utilized in the petrochemical industry, and these cables have the potential to come into contact with hydrocarbons such as oils, solvents, gases, and other chemicals. In the petrochemical industry, cable systems are considered to be of critical importance.
Lead-encased cables have long been the go-to choice in the industry for providing the highest level of protection possible for the interiors of cables, which are exposed to a wide variety of potentially damaging substances.
For a wide variety of petrochemical endeavors, low, medium, and instrumentation cables can benefit from the addition of a lead sheath that functions as a chemical barrier. The following are some of the benefits that lead-sheathed cables offer:
- Defensible barriers to prevent the introduction of hydrocarbons.
- protection against the penetration of moisture.
- Earthing and grounding capabilities are available with this system.
- Excellent corrosion resistance.
The drawbacks of using cables that are encased in lead
There are certain drawbacks associated with lead coated cables, in addition to the benefits that they offer. Lead is a type of metal that is both heavy and soft.

The hefty weight of this metal is considered a drawback because it increases the amount of labor required to install it, which in turn drives up the cost of doing so.
The use of lead in underground cable systems raises further ethical and environmental considerations. Because of its negative health effects, the use of lead in soil is strictly regulated in several Scandinavian nations.
Options available other than lead-sheathed wires
Because of these worries, companies that create products for the industry have suggested alternatives to cables that are wrapped in lead.
Some of the designs for lead-free cables consist of an inner layer of longitudinal aluminum that is bound with a sheath made of HDPE (High-Density Polyethylene) and a cover made of PA (Polyamide).
The lighter weight of lead-free alternative cable designs and their smaller diameters, both of which might be advantageous during the installation process, are two of the advantages of lead-free design alternatives.
A sheath made of aluminum, high-density polyethylene (HDPE), and polyamide (PA) performs the same functions as a sheath made of lead.
The Many Benefits of HDPE
HDPE is a recyclable plastic that offers a wide range of benefits and is simple to process in recycling facilities. The following are some of the many benefits of using this plastic:
- It is not only light but also quite sturdy.
- It is resistant to impact and can take a punch in the face without breaking.
- It has a long lifespan and is resistant to the effects of weather.
- It is not susceptible to the growth of mold, mildew, or rot.
HDPE is a material that is utilized in many different industries as an alternative to the use of heavy metals. For instance, HDPE is utilized in the construction of fuel tanks in the car sector.
Our suggestions are to either use lead or plastic.
Sheathed-in lead cables are still commonly employed within the industry today and have a demonstrated history of being successful in their use.
Because of the consistent performance of lead-encased cables, this design is typically selected for crucial applications in the petrochemical industry.
Designers and installers trust the performance of these cables. In addition to this, there is not yet a great deal of experience with the alternatives.
The decision to use cables encased in the lead is one that can be understood, and in some circumstances, lead is the only viable option.
electrical cable types
We recommend the plastic sheath as an option whenever the conditions at a place are adequate for both types of sheathed cables. The following are some of the reasons for this recommendation:
- It is not affected by water or other potentially damaging substances.
- It has a comparable amount of time.
- Due to the fact that it weighs less, the cost of transportation and installation of the cable is reduced.
- Most importantly, it has a much lower impact on the surrounding ecosystem.
The Difference Between Wiring with a Lead Sheath and Wiring with Cleats
As is common knowledge, the wiring system poses a threat to human life, and if it is not done correctly, the task can be extremely hazardous.
There is a wide variety of diversity within the field of electrical wiring systems. Let's have a look at the many kinds of electrical wiring that are utilized in the electrical systems of homes, businesses, and other types of domestic properties.
Understanding a few of the fundamental phrases used to describe wiring systems will be facilitated by familiarity with wiring technology.
Conductors can come in many forms. One form is electrical wiring, which is an example of a material that transmits electricity.
The majority of the wire that is used in our home application and in some other applications is insulated, which means that it is covered in a layer of non-conductive plastic. This is the case in some other applications as well.
In order to facilitate a deeper comprehension of this matter, the following section of this article explains the key distinctions between lead-sheathed wiring and cleat wiring.
How does cleat wiring work?
Wiring for cleats is typically made out of wires insulated with PVC or regular VIR, which are then braided and compounded.
Because this kind of wiring is best suited for temporary wiring needs, like those found in marriage halls, certain events, and certain functions, among other places, the most significant benefit of this wiring system is that it reduces the amount of money spent on labor and installation.
Therefore, this kind of wire is very vital. Furthermore, it can be erected relatively easily, and the materials may be reclaimed for later use.
The following is a list of the primary distinctions that can be made between lead-sheathed wiring and cleat wiring:
- The cost of wiring in the lead sheath is quite low, however, the cost of wiring in the cleat is high.
- The lead sheath wiring has a very long life, in contrast to the very short life of the cleat wiring.
- The protection that the lead sheathed wiring provides against fire is excellent, whereas the protection that the cleat wiring provides against fire is subpar.
- The following items are necessary for lead-sheathed wiring: wooden boards, screws, clips, joint clips, boards, round boards, teak wood batten, and so on. When in cleat wiring, the necessary materials include clear VIR or PVC wires, screws, blocks, boards, and gutters.
- Both of these conditions need to have a low voltage (250 v).
- The mechanical protection offered by lead encased wiring is above average, whereas the mechanical protection offered by cleat wiring is below average.
- The appearance of lead sheathed wiring is satisfactory, whereas the appearance of cleat wiring is unsatisfactory.
- When working with lead sheathed wiring, skilled labor is necessary, however, when working with cleat wiring, semi-skilled labor is required.
- Lead sheathed wiring offers a high level of protection against dampness, in contrast to cleat wiring, which offers no such protection.
- While using lead-sheathed wiring, making additions or alterations to the existing wiring is not overly difficult. On the other hand, when using cleat wiring, making additions or alterations to the existing wiring is fairly simple.
- The number of points that can be wired in a day by a wireman and a mate using lead sheathed wiring is four, while the number of points that can be wired using cleat wiring is six.
- The generation of the lead sheath wiring is somewhat weak, but the generation of the cleat wiring is poor.
Due to the high cost of lead-sheathed wiring and the severe consequences of a short circuit in the event that it leaks, this type of wiring is typically reserved for servicemen and other similar professions.
Cleat wiring, on the other hand, is used for temporary installations such as those at functions, weddings, and other similar events.
