注:
1、該產品可按用戶的使用要求，設計成具有阻燃性能或耐火性能的產品。訂貨時只需在原型號前加“ZR-”表示阻燃型，加“NH-”表示耐火型；
2、電纜的金屬屏蔽可按用戶要求有兩種形式:金屬絲編織或金屬帶繞包；
3、如需軟芯導體的電纜，應在原型號后加字母“R”。
Note:
1: We also produce cable with fame resistant performance or fire resistant performance accordina to the reauirement of customerPrefix “ZR-”should be added to the original type for flame retardant cable and “NH-" added for fire-resistant cable.
2: There are two kinds of metallic shielding. One is metallic wire braiding shielding. The other is metallic tape wrapped shielding.
3: Prefix“R”should be added to the original type for ordering cable with soft conductor;
