Xi Peiyi Italy Co., Ltd (CPE ITALIA S.P.A) once provided earthing device, can protect the transmission system of fragility like this.
This device is fastened on the cable by the stainless steel outer envelope by the ripple corrosion resistant plate that is in inside center, between stainless steel outer envelope and ripple corrosion resistant plate rubber ring is arranged, and plays good waterproof effect, avoids electric leakage and corrosion-resistant.
Inner link is to have stainless corrugated sheet to be connected with coaxial cable, by means of a suitable outer cable that draws, connects the metal structure of tower, if lightning is patronized, electric current will pass the outer surface of coaxial cable, earthing device, and metal tower, and link ground.
Although this device has proved its function in the use in several years, still need improvement and perfect in structure and mounting portion.
As for concern to structure, there is main place, several places to rethink, also improved properties of product and inner complexity:
1, Nei Bu complexity;
2, as time goes by, external cable be connected the center and carry out ways of connecting by welding, increased resistance, and weakened the use effect of electric current and equipment;
3, rubber ring makes equipment that the effect of waterproof be arranged, and meets the IP67 standard, and rubber ring is by EPDM T60 mold injection, and hardness has 60 shore hardnesses, and this means needs 0.2 time/square centimeter pressure to come moulding.This use to production time and equipment has caused high flow rate.
Install and must consider Several Factors, metal tower has the height of 10-30 rice, therefore just must consider fitting operation personnel's safety.
Lightning protection earthing protective device of the present utility model has carried out research to above problem and has improved.
