For installation in dry, damp or wet environments, in workshops with explosive atmospheres: it can be immersed in fresh water up to 10m depth and it could be used as energy supply cable for submersed pumps. Not suitable for underwater power transmission or installation in a waterway or where mechanical damage might occur and cause hazard. For connections liable to moderate mechanical stresses, i.e. industrial or agricultural workshop apparatus, large boilers, heater plates, electric tools such as drills and disk saws, electric appliances, portable motors and generators on building sites; also for fixed installations along floors or shelving on temporary job sites, for connecting structural elements in lifting apparatus, machinery, etc. Suitable for applications up to 1kV for adequately protected fixed installations (i.e. inside pipes or equipment) as well as for rotor connections to lifting equipment motors.

Manufacture Supervision 

1.Supervise manufacturing basis

Refer to the former Ministry of power Industry, Ministry of Machinery Industry issued by the electricity Office (1995) No. 37 "Interim Provisions for the quality supervision of large power equipment", "General representative group working Regulations in large power equipment manufacturers"

2.Manufacturing supervision method

Document witness, on-site witness and shutdown pending inspection, namely R point,W point , and H point.

After each manufacturing supervision content is completed, the supplier and the manufacturing supervision representative will complete the signature procedures on the witness form. The supplier shall submit one copy to the demander's manufacturing supervision representative.

R point:The supplier only needs to provide items of inspection or test records or reports, that is, document evidence.

W point:Inspection or test items attended by the purchaser’s manufacturing supervision representative, i.e. on-site witness

H point: When the supplier stops to wait for the inspection or test of the buyer's supervision representative, that is, the project is stopped for inspection.

Upon receipt of the witness notice, the demander shall promptly send a representative to the site of the supplier's inspection or test to participate in on-site witness or stop work for inspection. If the representative of the demander cannot attend on time, point W can be automatically converted to point R, but if point H is not agreed to be converted to point R by written notice of the demander, the supplier will not transfer to the next process and agree with the demander to change the witness time. If the buyer is still unable to participate on time after the change, the H point will be automatically converted to R point.

3. Requirements for suppliers to cooperate with manufacturing supervision

3.1 The supplier has the obligation to cooperate with the demander's manufacturing supervision and provide relevant information in a timely manner without incurring any costs.

3.2 The Supplier shall provide the demander's supervision representative with the convenience of work and life

3.3 The supplier shall inform the Buyer's representative of the equipment supervision project and time before witnessing the site or stopping work for inspection..

3.4 Demander's supervision representative has the right to check (borrow) the technical information related to the contract supervision equipment. If demander considers it necessary to copy and file, the supplier shall provide convenience.

3.5 The supplier shall provide the inspection and test records and reports to the supervision representative of the demander after the witness.
