A, product profile
The HL-01 type earthing module is a conductive non-metallic material as the main body, it by grounding body electrical conductivity, the chemical stability good nonmetal materials, metal grounding body, electrolyte and moisture absorption agent composition, main application range:
1, power plants, substations and switching, high voltage transmission lines, electrified railway, telecom, mobile, communication stations, microwave base station, ground satellite receiving station in, such as grounding, safety work radar station grounding and lightningproof grounding;
2 and precious precision instrument, computer room equipment, post and program-controlled equipment, radio and television equipment, electronic medical equipment grounding and protection work grounding;
Three, all kinds of high building and tall buildings, structures, and places of high monument and other lightning grounding;
4, oil pipeline and YouQiGuan, inflammable and explosive material warehouse lightningproof grounding.
Second, working principle
The HL-01 type earthing module built-in galvanized steel with the ground, protected ground wire, the metal with the earth grounding body the area of effective contact will greatly increase, and because the HL earthing module have very strong moisturizing, hygroscopicity and stable electrical conductivity, therefore, metal with the earth grounding body will greatly reduce the contact resistance, so as to fully realize the earthing module resistance reduction purpose.
Second, performance characteristics
1, this module USES a conductor material as the module of nonmetal conductive medium, and its electrical conductivity don't get season influence;
2, can absorb wet protect wet, can maintain and soil effective contact grounding resistance, low;
3, in high resistivity areas, can effectively reduce the earth network grounding resistance;
4, a great work frequency and impact resistance, resistance stability; current shock
5, corrosion resistance, non-toxic, long life, easy installation.
Three, technical index
1, model: the HL-01;
2, appearance size: 500 * 400 * 60 mm / 900 * ф 150 mm; 1000 * 1000 * 150 mm/ф ф 200 mm mei ф pattern: 1000 * 1000 * 260 mm/ф ф 150 mm
3, quality: 20 KG / 28 KG; 50 KG / 90 KG.
4, at ambient temperature resistivity: more than 3 ohms m.
5, industrial frequency grounding resistance: 8.5 ohms (soil resistivity in changsha city typical suburban take soil 57 ohms m.)
6, estimate type: Rj ≈ 0.15 p
Four, dosage calculation
According to the soil mechanical soil resistivity, adopt type HL-01 calculation of earthing module usage:
Level for a single module, buried grounding resistance:
After the parallel total grounding resistance: Rnj = Rj/n
Type: P-soil resistivity (ohms m.)
A, b-the HL-01 type earthing module the length, width (m)
Rj-a single module grounding resistance (ohms)
Rnj-total grounding resistance (ohms)
N-the number of earthing module
G-module adjustment coefficient, generally take 0.6 0.9.
Six, construction method
1, the HL-01 type earthing module level for the buried depth, buried for not less than 0.8 m.
2, the distance between the module not less than 4 m.
3, a core modules each other with parallel or ground wire, had better use welding, welding length is twice the width of attachment. 3

4, should be removed from the welding place welding slag, with anticorrosive conductive paint or package the HL long-term anti-corrosion type grounding resistance reduction agent;
5, solid the filled soil water should be moderate, layered ramming, stay module full moisture absorption (24 hours) after grounding resistance measurement.
Seven, the matters needing attention
1, storage module should maintain a certain humidity, avoid high temperature, dry, exposure to the sun;
2, transportation and installation, should avoid to mechanical force injury module.
3, in cold areas, should be buried in a belt of the module.
