Dear Sirs,
Two years ago we had the pleasure of supplying you with a number of switchgear. Since then we heave received no order form you. Perhaps our previous did not fit your requirements.
Now we wish to inform you that we have just introduced our latest high voltage switchgear on to the market. Our research engineers have finally come up with the answer to some of those problems you had with high voltage currents. The present product is insulated with a special resin which is as tough as metal,cracking-resistant,and very economical,and has passed test after test run by our engineers. We are enclosing specifications and a price list for you consideration and hope to receive an early order from you as other buyers are showing their great interest in this product.
Yours sincerely,
