Before we dive into   what is a deep cycle battery , it is first important to understand a few battery basics of what a cycle is, what depth of discharge means, and what it really means to deep discharge a battery. One full cycle is considered a full discharge and recharge of a battery. What is meant by a full discharge? Discharge is measured by the capacity removed from the battery – the depth of the discharge (DoD) is used to indicate how much of the battery capacity has been used during a single discharge. A full discharge is 100% DoD. What is a Deep Cycle Battery? This answer may seem obvious, but a deep cycle battery is a battery that has been designed to continuously handle deep discharges of 80-100% DoD. Does this mean high-rate batteries can’t be used for a deep discharge? Yes and no. One or two deep cycles will not hurt the battery (if maximum discharge and charge rates are strictly adhered to), but this is where the design of the battery matters because a high-rate battery wo

A circuit breaker  is a switching device that can be operated manually or automatically for controlling and protecting the electrical power system. Vacuum Circuit Breakers use vacuum as the interrupting medium due to its high dielectric and diffusive properties. Read this new blog in Linquip to know more about this type of circuit breaker and Its applications. What is Vacuum Circuit Breakers? Vacuum circuit breakers  are compactly designed for safe operation, high reliability, and easy maintenance, and find a use for various types of high voltage circuits. They interrupt an electric circuit to prevent unwarranted current, caused by a short-circuit, typically resulting from an overload. There are mainly five types of circuit breakers, generally used as protective equipment of high voltage system: Oil Circuit breaker (OCB) Minimum Oil Circuit breaker (MOCB) Vacuum Circuit Breaker (VCB) SF6 Circuit Breaker Air Circuit Breaker (ACB) Vacuum Circuit Breaker Operation It is an electrically op

    Different terms used for  arresters  are sometimes confusing even professional engineers and electricians use them interchangeably. Now let’s discuss all these arresters in details.   Table of Contents   What is a Surge Arrester? What is a Lightning Arrester? Main Differences between Surge Arrester and Lightning Arrester Should You Use Surge Arresters or Lightning Arresters?   Surge Arrester   1. The  surge arrester  will be installed nearer to the equipment to be protected and the transmission tower line enter in to the substation point. 2. It protects against high voltage transient (example: lightning strike on the transmission conductor) typically, it is indirect protection of lightning strikes. 3. It should be installed each phase of the circuit. i.e if you have 2 parallel switch yard then you should install 6 number of surge arrester (first run 3 phase and second run 3 phase) . Lightning arresters   1. The lighting arrester is doing the exact duty of surge arrester from outsid

  What is selective laser melting in 3D printing? Selective laser melting (SLM) is a special 3D printing technique that uses a high power density laser to fully melt and fuse metal powders to produce near full density (up to 99.9% relative density) near net shape parts. Processing Craft The technology SLM is short for selective laser melting, which the rapid prototyping technology for the metal powder. SLM can directly form the metal parts which is close to fully dense, and needn’t binders. Hence, this technology is also called  direct metal laser sintering , or  DMLS  for short. The accuracy and mechanical properties of prototypes which made by SLM is better than SLS, so it’s becoming more and more popular in 3D printing. How the SLM process work？ SLM technology need make the metal powder melted completely, and form the metal parts directly, hence the high-power laser is required. Before the high-power laser beam start scanning, the horizontal powder roller need spread the metal powde

Everyone knows they keep you warm, but the benefits of wearing a   wetsuit   go far beyond temperature. When you think of wetsuits, the first thing that comes to mind is probably the need to stay warm while swimming in cold water. After all, that's why they were invented. The average wetsuit is designed to keep you warm while submerged in water that can range from 50 to 70 degrees, depending on the style and thickness. But in reality, wetsuits have many other benefits that are easily overlooked.   Benefits of Wearing a Wetsuit for Inner Peace One of the benefits of wetsuits is that they can actually relieve stress and help you perform better. Knowing that your body will remain at a very comfortable temperature allows you to focus more on your actual performance rather than how you feel during that performance. Emphasizing physical comfort and temperature can make it harder to feel excited about the activity you are about to perform. Wetsuits can solve this problem, especially if yo

Prepainted galvanized steel coil  is a kind of colour coated steel coil (PPGI coil). It uses galvanised steel as the base metal. The zinc layer is highly resistant to corrosion. Together with the coating, it is more durable than galvanised steel. The metal coated steel then undergoes a number of cleaning procedures, pre-treatment solutions and finally a multi-layer organic coating including laminates, vinyl dispersions and paint. This continuous technique of applying different coatings is known as coil coating. As a result, the steel coil is used in the finished product without the need for painting or finishing.   PrePainted Galvanized Steel Coil (PPGI) and Pre-Painted Galvalume Steel Coil (PPGL) is a kind of building materials, with galvanized sheet and aluzinc sheet as the substrate, after pretreatment (degrease and chemical treatment) and liquid dope with several layers of color, then firing and cooling, finally the palte steel is called pre-painted  galvanized steel coil  (PPGI) o

  The limits of height you can build a gabion rock retaining is really only limited to your needs.   Gabion baskets  can be used to divide or step gardens by as little as 300mm or can be used to build a side of a house. It all comes down to stability and above a certain height, engineering approval. Find out more detail on considerations of how high you can build a retaining wall here.   Here are 4 common approaches to think about when determining the height of your rock retaining wall: 1. Add additional baskets to increase the depth of the wall.   This increases the surface area of the base of the wall on the ground which reduces the opportunity for the wall to sway or collapse. The recommended ratio is 2 baskets high to every 1 basket deep. Gabion Basket 2. Install support posts.  Support posts help add stability to your wall to also reduce the risk of collapse. They need to be strong enough to properly support the gabions and should be secured in a concrete slab underneath the baske
