A, 500 * 400 * 60MM Ground modules: a main conductive grounding
non-metallic materials, which consists of electrical conductivity,
chemical stability, good non-metallic materials, metal grounding,
electrolyte composition and hygroscopic agents, is grounded projects in recent years the most commonly used scientific methods,
according to its soil conditions, amount of ground to install the
module, you can achieve the requirements of grounding resistance1,
the use of grounding resistance reducing the module, both to
minimize the ground resistance, but also to ensure long-term stability of grounding, the use of period
greater than 60 years, which has a moisture, moisturizing
properties, low grounding resistance and can maintain long-term
stability, the impact of repeated high-current, the resistance of
small increases, and no hard, hair brittle fracture phenomenon, with the reduction agent has obvious
advantages compared to withstand -40low temperature, northern cold
areas apply.
Second: The main application
1, power plants, substations, switching stations, high voltage
transmission lines, electrification of railways,
telecommunications, mobile communications base stations, microwave
relay stations, satellite ground receiving stations, radar and
other ground work, security, grounding and lightning protection
grounding.
2, expensive precision instruments, computer room equipment,
telecommunications equipment, program-controlled, radio and
television equipment, electronic medical equipment and protective
earth ground work.
3, the largest variety of high-rise buildings and structures,
landmarks of ancient buildings, such as lightning protection and
grounding the tall monument.
4, oil pipelines and oil and gas cans, flammable material storage
Lightning Protection.
Third: How it works
Grounding module built-in thermal galvanized flat steel, and other
grounded metal materials to facilitate the effective access,
increased contact area of the grounding and grounding module
moisture, moisture absorption and stability of the conductivity of
the purpose to achieve better reduction in resistance.
Four: Features
1, the use of chemical stability of non-metallic conductor material
as the module's conductive medium, the conductivity is not seasons.
2, to moisture absorption, to maintain effective contact with the
soil, ground resistance is low.
3, in high soil resistivity areas, can effectively reduce the
grounding resistance.
4, frequency and impact resistance to a large current surge,
resistance and stability.
5, corrosion-resistant, non-toxic, long life, easy to install.
6, can withstand -40low temperature, northern cold areas apply.
Five: Construction Methods
1, the ground vertically embedded modules, ground level of embedded
modules. Buried depth of not less than 0.8 meters.
2, module spacing of not less than 5 meters.
3, the module in parallel with each other or very core and ground
connected, welding, welding area more than 2 times the body
connection.
4, should be cleared at the welding slag in welding and coated with
anti-corrosion paint conductive paint or asphalt.
5, the backfill should be adequate watering, compaction in layers
until the module is fully moisture (24 hours) after the measurement
of grounding resistance.
VI: Attention
1, the storage module should maintain a certain humidity, avoid
high temperature, drying, exposure.
2, the transportation and installation, to avoid mechanical damage
module.
3, in the cold regions, the module should be buried in the
permafrost below.
