Flexible grounding module product is a kind of conductive non-metallic materials mainly grounding body, it is composed of conductive, stable non-metallic minerals and strong conductive materials. It is a special product for reducing grounding resistance, suitable for various types of soil environment, and has significant advantages in high soil resistivity areas. It is mainly used as grounding body for "building ground", "lightning protection grounding", "anti-static grounding", "ac working ground", "safety protection grounding" and other purposes. Its birth created a new era of grounding materials and grounding technology. Compared with the traditional grounding body, this product has high efficiency of resistance reduction, grounding resistance stability, reduce the ground potential counterattack, long service life, corrosion resistance, avirulent environmental protection, convenient installation, widely used in lightning protection grounding, safety protection grounding, communication work, dc grounding and anti-static grounding, shielding and other special grounding.
Counterpoise the grounding resistance is mainly composed of grounding body and connected to the material itself resistance, and grounding body contact resistance of the soil around and into the current spread in the soil resistance, the grounding body and the contact resistance of the soil and into the current spread in the soil of current is the main part of the grounding resistance, accounting for over 98% of the grounding resistance. Traditional grounding bodies are mostly metal conductors, such as flat steel, round steel, Angle steel, steel pipe, copper rod, and copper plate. It is difficult to solve the problem of grounding in the condition of high soil resistivity because the grounding resistance is not stable enough and the service life of the grounding network is relatively short. The flexible grounding module is mainly made of metal materials with good conductivity and stability, and the surface of the metal material with anti-corrosion treatment is used as the skeleton, which is extruded by special equipment. Compared with traditional earthing, this product has the following remarkable features:
1, to reduce the contact resistance, the main body of flexible earthing module material similar to the physical structure of the soil, can combine with soil as a whole, make the grounding body and soil area of effective contact many times larger than the metal grounding system, enlarges the area of effective diffuser earthing body, greatly reduce the contact resistance of grounding body and soil, therefore can significantly improve the efficiency of ground, reduce fixed occupation of land area.
2, stability: the flexible grounding module itself has a strong moisture absorption and moisturizing ability, so that the soil around it remains wet, to ensure that the grounding module effectively play a conductive role; At the same time, the conductive properties of the conductive material in the grounding body are not affected by seasonal changes such as dry humidity, high and low temperature, thus providing a stable grounding resistance.
3, reduce the potential counter: flexible grounding module of nonmetal materials to make resistivity varies widely between the metal and soil forming a change quite gentle area of low resistance when large current shock, can reduce the earthing body, grounding line transient potential gradient, reduce the step voltage and touch voltage, reduce the probability of local potential counter.
4, long service life: the main body of the flexible grounding module itself is anti-corrosion material, its metal skeleton is the surface of the anti-corrosion treatment of metal materials, so the overall corrosion resistance of the grounding body is excellent, the service life of more than fifty years.
