SY-D Equipotential connector

Working principle and effect:

Reduce contact resistance

Resistance stability

Reduce potential counterattack

Performance characteristic:

1.Corrosion resistance, non-toxic, long service lifetime, convenient to install, reduce construction work

2.It can be moisture absorption and moisture, grounding resistance is low.

3.Resistance to large current shock but resistance doesn't grow, no harden, sent fragile, fracture phenomena.

4.It can be reduced the high resistivity soil of grounding resistance effectly.

5.Grounding resistance is influenced very little by season. The resistance can keep stable for a long time.

Technical parameter:

model	exterior	quality	industrial frequency ground resistance	resistivity under room temperature
SY-D-01	500*400*60(plate-type)	20kg	≤8.5Ω	≤3Ω.m
SY-D-02	Φ150*850(cylinder)	20kg	≤8Ω	≤3Ω.m

Dosage caculation:

N=ρ*M/Rn*K

ρ----soil electric rate

M----module grounding coefficient(numeric area:0.11-0.15)

Rn----counterpoise design and grounding resistance

K----utilization coefficient(numeric area:0.7-0.85)
