Structurally, the polymer anode grounding device consists of an electrode made of polymers resistant to oil, petroleum products, anode dissolution products, and gases, with a low specific electrical resistance not exceeding 1.0 Ω·m, containing a tinned flexible copper conductor placed along the central axis. The ends of the electrode are connected to a KGN-KHL EHZ-U cable through a contact assembly that includes a sealing element and polyolefin heat-shrink sleeves resistant to ultraviolet radiation and aggressive environmental conditions.

Improved operational reliability of the polymer anode grounding device within cathodic protection systems for buried metal structures is achieved through the use of electrodes with low specific electrical resistance, providing exponential distribution of protective current across the entire surface of the active element.

Repairability of the polymer anode grounding device is ensured by the use of an installation casing filled with conductive gel.

Two installation configurations of the repairable anode grounding device are available: horizontal and vertical.

In addition to enhanced performance characteristics, the service life is extended to not less than 50 years.

The project for establishing the production of repairable anode grounding devices using conductive polymers with reduced resistance was implemented with the support of the Foundation for Assistance to Small Innovative Enterprises in the Scientific and Technical Sphere (Innovation Support Fund), grant agreement No. 759ГКС4/70981 dated 17.11.2021.

It performs two critical functions: ensuring high reliability during transportation and installation, and promoting efficient distribution of the anode current. The mounting handle is an integral part of the grounding device, providing convenience during work in soil and facilitating handling operations. The casing of this device degrades during direct operation in soil.

Applications

The active element made of titanium with MMO coating is placed inside a titanium protective casing (PAZ.KMG.T) with a diameter of 16 cm and a length of up to 220 cm. The standard configuration of PAZ.KMG.T includes a cable lead with a length of 2 m.

To prevent backfill loss during storage, the backfill is evenly distributed along and across the active element to ensure reliability during transportation and installation, as well as unrestricted current distribution from the active surface.

The casing dissolves rapidly when placed in any type of soil, which facilitates installation and handling operations due to the presence of a special mounting handle made of cotton material. The length is determined according to specific customer requirements specified in the technical documentation.

In the standard configuration, the cable lead length is 2 m. The protective casing prevents backfill loss during storage. It shields the backfill from adverse impacts and helps ensure uniform distribution along the active element.

Once the PAZ.KMG.M magnetite anode grounding device, which can be ordered from us, is ready for operation and placed in soil, the protective casing dissolves rapidly, allowing the backfill to disperse and begin interacting with the surrounding medium to provide effective corrosion protection.

The mounting handle enables quick and safe placement at the required location, as well as easy repositioning when necessary. It ensures secure and reliable handling during transportation and installation.

Ordering GAZ.KMG.F type magnetite deep anode grounders from our website provides a ready-to-use set without additional modifications. It is suitable for insertion into soils with high electrical conductivity. When installed in a borehole, the element should take a vertical position.

Technical Description

The design of magnetite deep anode grounders GAZ.KMG.F includes a special casing that serves as a container for the magnetite electrode surrounded by a coxo-mineral activator. The casing ensures safe transportation and installation. During operation, the container dissolves.

The casing is securely fixed with guide brackets. This is necessary to connect complete deep grounders into a chain to increase current capacity and reduce transition resistance. No more than 24 blocks can be included in a chain.

The venting of gases generated during operation of GAZ.KMG.F magnetite deep anode grounders is managed using a gas outlet tube. Together with the cable system, it is brought to the surface. The gas outlet tube is perforated along its length and manufactured to order, with one tube per working element installed in a single borehole.

The customer determines the number and components of the deep grounding system, specifying how many blocks will be installed and the length of connection cables and drainage tubes. The equipment is selected according to the prepared cathodic protection project.

The complete grounders reach operational mode and low current dispersion resistance in minimal time. The equipment does not require additional modifications, significantly simplifying installation of the anode grounders.

Each block is equipped with a connection cable. The cable length depends on borehole depth and installation height of the element. The cable has no joints and is brought to the surface for connection to the anode line cable. Pricing and delivery terms can be obtained by contacting our manager.

GAZ-FK is secured in a special bandage that ensures firm attachment and allows installation of complete anode grounders into a borehole and immersion to the design depth. The device prevents corrosion and simplifies installation. GAZ-FK deep ferrosilicon anode grounders can be positioned horizontally or vertically without altering operational properties.

The deep grounding installation process involves using specialized drilling equipment to create vertical boreholes or horizontal trenches to a specified depth. Metallic electrodes are installed into these boreholes or trenches to effectively dissipate electrical current into the ground. Proper placement and depth of these electrodes reduce grounding resistance and ensure system electrical safety.

Technical Description

The deep grounder is a block-assembled structure with a high degree of factory readiness, meaning no additional modifications are required and it is ready for immediate installation.

Deep grounding is a method of creating effective electrical grounding using a grounder installed at significant depth underground. It reduces grounding resistance and prevents damage to underground metal structures.

The deep grounder block consists of two sections forming its base. Each section contains two ferrosilicon electrodes connected via a special connection cable. A single connection cable ensures effective current supply.

The sections of the deep grounder block are joined with a looped connection. During transportation, sections remain connected, but during installation they are aligned coaxially. This approach optimizes installation and ensures proper positioning for anode grounding.

This block design offers several advantages: high grounding efficiency reducing corrosion, ease of installation, and reliability in operation.

Two connection cables are brought to the surface from the borehole to connect the deep grounder block to the electrical system, providing current supply and system integration.

A feature of the deep grounder block design is their connection in a garland to increase current capacity and reduce transition resistance, important for effective grounding.

The allowable number of deep grounder blocks per borehole is 4, creating optimal conditions for reliable anode grounding.

Connecting blocks in a garland efficiently uses borehole space and maximizes system current capacity, useful where ground access is limited or high grounding efficiency is required.

A special gas outlet tube is used for venting gases generated during operation of GAZ-FK deep ferrosilicon anode grounders. Along with main cables, it is brought to the surface.

The gas outlet tube is perforated along the garland length for uniform gas distribution and timely surface venting, preventing bubble formation.

Supplies are made to specific orders. One tube is allocated per garland, which is installed in a single borehole. The tube length is sufficient for borehole immersion.

The space around the anode is filled with coxo-mineral activator to reduce current spread resistance, accelerating electrode dissolution efficiency.

The coxo-mineral activator improves grounding efficiency and reduces grounder resistance, consisting of a mixture of crushed coke and mineral binder, such as clay or cement.

The anode grounding system for GAZ-FK deep ferrosilicon grounders is selected based on cathodic protection project requirements, considering soil resistivity, site conditions, and technical-economic parameters.

The number of blocks per borehole, their quantity, and spacing are determined according to project 327.T-AZ, specifying block placement based on soil resistivity and required protection level.
