Quatation Inquiry (采购产品): Quatation Dear sirs, Dacon systems inc. (Santa Ana) gave us Your contact information, and advised You as manufacturer, who can make logging (geophysical) cable in accodance with our inquiry. I'll to explain You situation in a few words. Our company, Everlight Ltd from Saint-Petersburg, took part in tender on delivery of geophysical (logging)cables for State Concern Turkmengas (it's large serious company from Turkmenia). We received proposal from Dacon systems, and on it's base we gave our tender proposal. Prices were best, and we were the one, who proposed for delivery american cable. But when on the final stage of tender our Customer asked us to give full technical characteristics, we found out, that cable of Dacon Systems has no cable armature (no served shield), so it's not suitable for Customer. That's why we ask You to learn technical requirements (see attached file) and if You can manufacture such cable, please give us Quatation with prices and terms of delivery as soon as possible. As for technical characteristics, please pay attention, this cables are accounted on high mechanical loads and should have good capacity to carry out load. That's why it's extremely important to provide breaking strength 25,4; 28,9 and 70 kN for different types of cable (see attached file). So it's necessary to make cable armature (served shield), we send You the picture similar to what we need (it has served shield of galvanised steel wire, but You can make it from other material, if it will answer mechanical characteristics from requirements). Besides, it's important to provide meanings of capacitance as described in requirments and temperature rating. As for other characteristics, You can change them a little (for example, you can decrease voltage from 1400 up to 1000 V, or You can make cable of smaller diameter, than it’s specified). In any case, please inform us, can You help us or not, and if yes, please do Your best to make Quatation and Data sheets for us as soon as possible. Please understand, it's real inquiry, cause we've already won tender, so we have good chance to start mutually advantegeous business cooperation with Your company.
